I have a test I don’t know what to do. Can someone please help me?

Answer:

180

Step-by-step explanation:

A = 16 + 25 + 36 + 49 + 64 + 81 = 271

B = 27 + 64 = 91

A - B = 271 - 91 = 180

Answer:

A=14.9

B=25.6

C=25.5

Step-by-step explanation:

[tex]\frac{25,5}{sin71} =\frac{14.9}{sin^{0} } \\\\sinx^{0}=\frac{14.9 sin 71}{25,5} \\\\x=sin ^{-1}(\frac{14.9 sin 71}{25,5} \\\\x=33.54\\\\[/tex]

[tex]180-71-33.54=75.46 \\\\B:\frac{b}{sinB} =\frac{25.5}{sin71} \\[/tex]

[tex]b=\frac{25.5 sin 75.46}{sin 71} \\\\b=26.106\\\\b=26.1\\\\x=33.54[/tex]

hope it helps...

have a great day

since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.

p = 1/8 + 15/16

Use common denominator, which is 16:

p = 1(2)/8(2) + 15/16

p = 2/16 + 15/16

p = 17/16

17/16 is an improper fraction. If you want to use a mixed number for your answer, then:

17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)

120= 6.28r

r= 120/6.28

r= 19.10 m

Hence the diamter D

Answer:

No, they are not similar

Step-by-step explanation:

The three triangle angles should always add up to 180 degrees.

In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.

In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.

In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

Isosceles triangle

Step-by-step explanation:

Given

Two congruent angles and two congruent sides

Base on the given description, the concept being described is an isosceles triangle, as it has two congruent sides and two congruent angles.

If each angle measures 45 degrees each, then the third angle is 90 degrees.

This is shown below.

[tex]\theta + 45 + 45= 180[/tex] --- angles in a triangle

[tex]\theta + 90= 180[/tex]

Subtract 90 from both sides

[tex]\theta = 90[/tex]
