Three angles are in the ratio 2 : 3 : 5. The smallest angle is 50⁰.Work out the sizes of the other two angles.

Step-by-step explanation:

given,

the complete angle is complementry angle which is 90°

let the first angle be x and second angle be 7x ( as second angle is 7 times more than first angle )

now,

→ x + 7x = 90

→ 8x = 90

→ x = 90/8 = 11.25

therefore

1st angle = x = 11.25°

2nd angle = 7x = 7 × 11.25 = 78.75°

hope this answer helps you dear take care and may u have a great day ahead!

Answer:

  see attached

Step-by-step explanation:

The equation is in vertex form, so you can tell that the vertex of the graph is (x, y) = (-4, -8). This suggests your table should have values that are symmetrical about x = -4. The attachment shows one possible table of values.

__

It is generally convenient to let a graphing calculator or spreadsheet compute a table of values for you.

Put each chosen value of x into the equation and do the arithmetic.

  For x=-5, ...

  y = 3(-5+4)² -8 = 3(-1)² -8 = 3 -8 = -5

Then (-5, -5) will be a point in your table. Recognizing the symmetry of the function, you know that (-3, -5) will also be a point in your table.

Answer:

y = 3x + 19

Step-by-step explanation:

Point slope formula: y-y1=m(x-x1)

y - 4 = 3(x - (-5))

y - 4 = 3(x + 5)

y - 4 = 3x + 15

y = 3x + 19

SSS

side- side- side

when all 3 sides are congruent, then the triangles is congruent.

ML and NP are given.

MP is shared (so, definitely even the same side).

and PL and NM are parallel.

so, all 3 sides are covered.

Step-by-step explanation:

the circumference of a circle is

c = 2×pi×r

with r being the radius.

the diameter of a circle is always twice its radius.

circle A

2 2/3 = 8/3 = 2×pi×r

4/3 = pi×r

r = 4/3 / pi = 4/(3×pi) = 0.424413182... m

the diameter is then : 0.848826363... m

the diameter of B is 1.5 times the diameter of A :

1.273239545... m

therefore, the radius of B is 0.636619772... m

and so, the circumference of B is

2×pi×0.636619772... = 4 m

of course, if we had considered that both diameter and circumference are in linear dependence (see the formula for the circumference), we could get the result much faster. if the diameter increases 1.5 times, then also the circumference increases 1.5 times :

2 2/3 = 8/3 × 1.5 = 8/3 × 3/2 = (8×3)/(3×2) = 8/2 = 4 m

Answer:

check explanation

Step-by-step explanation:

the slope between two points can be defined as the change in y over the change in x. Consider (0, 11) as your first point and (1,4) as your second point.

To find the slope, do:

(y2 - y1) / (x2 - x1) = slope

(4 - 11) / (1 - 0) = slope

-7/1 = slope

Divide both sides by A .

Hence the value of A should be 8 .

Answer:

See below.

Step-by-step explanation:

Since there is an equal sign, this is not an expression. It is an equation. If you evaluate the right side, you'll see that it is a false equation since both sides are not equal to each other. Also, there is a bracket missing.

90 is not equal to 4.55.

Maybe it is meant to be the following expression:

90 + [(82 - 77).91] = 90 + 5(0.91) = 90 + 4.55 = 4.55

Or maybe this one:

90 - [(82 - 77).91] = 90 - 5(0.91) = 90 - 4.55 = 85.45

Answer:

Since angle 1 = angle 3 (vert opp angles),

angle 1 = angle 3 = 180°-129° (adj angles on a str line)

                            = 51°

angle 4 = angle 2 = 129° (vert opp angles)

Hence,

angle 1 = 51°

angle 3 = 51°

angle 4 = 129°
