to convert from percentage to a fraction, you just put 100 and the bottom of that number;

Answers

Answer:

d−14=34 shows that when we add sold drawing we get the total drawings

Step-by-step explanation:

We have been given that Rosa brought d drawings to an art show.

After selling 14 of them, she had 34 left.

We have to form a equation such that when we add 14 in 34 we get the total of drawings.

d-14=34d−14=34 (1)

Equation (1) shows that when we add sold drawing we get the total drawings

Answer:

d-14=34. 34+14=48. 48-14=34 which is our total

a. name the vertex of <4 b. Name the sides of <1 c. Write another Name for <5 d. classify each angle

Answers

Answer:

A. vertex B

B. Side BC and BD

C. Angle EBD

Step-by-step explanation:

An angle is an undefined term in plane geometry.

The vertex of [tex]\angle 4[/tex] is BThe sides of [tex]\angle 1[/tex] are BC and BDAnother name for [tex]\angle 5[/tex] is [tex]\angle DBE[/tex].[tex]\angle FBC[/tex] is a right angle[tex]\angle EBF[/tex] is an obtuse angle [tex]\angle ABC[/tex] is a straight angle.[tex]\angle EBC = 144[/tex][tex]\angle ABE =13.5[/tex]

Vertex of [tex]\angle 4[/tex]

The vertex of an angle is the point where the rays that form the angle meet.

From the diagram, rays BE and BA meet at point B to form [tex]\angle 4[/tex].

Hence, the name of the vertex is B

Sides of [tex]\angle 1[/tex]

The sides of an angle are the rays or sides that form the angle

[tex]\angle 1[/tex] is formed by rays BC and BD

Hence, the sides are BC and BD

Another name for [tex]\angle 5[/tex]

An angle can be named by combining the sides and the vertex.

The sides of [tex]\angle 5[/tex] are DB and BE, while the vertex is B

This means that rays DB and BE meet at point B

Hence, another name is [tex]\angle DBE[/tex]

Classify the angles

Angles are classified based on the measure

[tex]\angle FBC[/tex] is a right angle, because [tex]\angle FBC = 90^o[/tex]

[tex]\angle EBF[/tex] is an obtuse angle because [tex]\angle EBF[/tex] is greater than [tex]90^o[/tex] but less than [tex]180^o[/tex]

[tex]\angle ABC[/tex] is a straight angle, because [tex]\angle ABC= 180^o[/tex]

Angle bisector

The line or ray that divides an angle into equal halves is an angle bisector.

Ray BE is an angle bisector, because it divides [tex]\angle DBA[/tex] into two equal halves.

Find [tex]\angle EBC[/tex]

We have:

[tex]\angle EBD = 36[/tex]

[tex]\angle DBC = 108[/tex]

[tex]\angle EBC[/tex] is calculated using:

[tex]\angle EBC = \angle EBD +\angle DBC[/tex]

[tex]\angle EBC = 108+36[/tex]

[tex]\angle EBC = 144[/tex]

Find [tex]\angle ABE[/tex]

We have:

[tex]\angle EBF = 117[/tex]

[tex]\angle DBC = 108[/tex]

[tex]\angle ABE[/tex] is calculated using:

[tex]\angle EBF = \angle ABE +\angle EBD + \angle ABF[/tex]

Where

[tex]\angle ABF = 90[/tex]

[tex]\angle ABE = \angle EBD[/tex]

So, we have:

[tex]117 = \angle ABE +\angle ABE + \angle 90[/tex]

[tex]117 = 2\angle ABE + 90[/tex]

Collect like terms

[tex]2\angle ABE =117 - 90[/tex]

[tex]2\angle ABE =27[/tex]

Divide both sides by 2

[tex]\angle ABE =13.5[/tex]

The measure of an angle is 3°. What is the measure of its complementary angle?

Answers

Answer:

87°

Step-by-step explanation:

if an angle is complementary that means that equals 90°.

and we know one part of the angles, so then we take 90° - 3° and we get 87°.

Answer:

The measure of its complementary angle is 87°

Step-by-step explanation:

We know this because the sum of two complementary angles is always equal to 90°, so:

90 - 3 = 87

Therefore, your final answer will be 87°

Use complete sentences. Source 1 "The government of Peru was a despotism, mild in its character, but in its form a pure and unmitigated despotism. The sovereign was placed at an immeasurable distance above his subjects. Even the proudest of the Inca nobility, claiming a descent from the same divine original as himself, could not venture into the royal presence, unless barefoot, and bearing a light burden on his shoulders in token of homage. As the representative of the Sun, he stood at the head of the priesthood, and presided at the most important of the religious festivals. He raised armies, and usually commanded them in person. He imposed taxes, made laws, and provided for their execution by the appointment of judges, whom he removed at pleasure. He was the source from which every thing flowed, all dignity, all power, all emolument. He was, in short, in the well-known phrase of the European despot, himself the state. William Hickling Prescott, American scientific historian, excerpt from History of the Conquest of Peru, 1847 Source 2 "By night and day they [human offerings] burned, supplied with fuel by an army of slaves who brought it on their backs over the long causeways that connected the island-city with the mainland and its distant forests. These pillars of smoke by day, and ill-omened banners of flame by night, were regarded with fear and hatred by many a dweller in the mountains surrounding the Mexican valley. They were the symbols of a power against which these had struggled in vain, of a tyranny so oppressive that it not only devoted them to lives of toil, hopeless of reward, but to deaths of ignominy and torture whenever fresh victims were demanded for its reeking altars. But while hatred thus burned, fierce and deep-seated, none dared openly to express it, for the power of the all-conquering Aztec was supreme. Far across the lofty mountains, to the great Mexican Gulf on the east, and westward to the broad Pacific; from the parched deserts of the cliff-dwelling tribes on the north, to the impenetrable Mayan forests on the south, the Aztec sway extended, and none might withstand the Aztec arms. If the imperial city demanded tribute it must be promptly given, though nakedness and hunger should result.
