Which pairs of polygons are similar? Select each correct answer. Two trapezoids. The trapezoid on the left has horizontal bases

at the top and bottom. The left leg is perpendicular to the bases. The right leg is slanted. The top right angle has a single arc and the bottom right angle has a pair of arcs. The top side is 7.2 inches, the right side is 27 inches, the bottom side is 18 inches, and the left side is 10.8 inches. The trapezoid on the right also has horizontal bases. The right leg is parallel to the bases. The left leg is slanted. The top left angle has a single arc. The bottom left angle has a pair of arcs. The top side is 4 inches, the right side is 6 inches, the bottom side is 10 inches, and the left side is 15 inches. Two rectangles. The larger rectangle has side lengths of 14 millimeters and 18 millimeters. The smaller rectangle has side lengths of 7 millimeters and 10 millimeters. Two triangles. In the smaller triangle, all three sides are 5 feet long. In the larger triangle, all three sides are 8 feet long. Two right triangles. One of the acute angles in each triangle has a single congruent arc. In the larger triangle, the sides measure 24 centimeters, 32 centimeters, and 40 centimeters. In the smaller triangle, the sides measure 18 centimeters, 24 centimeters, and 30 centimeters.

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times
erastova [34]

Answer:

1st ∡ = 15.5°

2nd ∡ = 77.25°

3rd ∡ = 87.25°

Step-by-step explanation:

1st ∡:  x

2nd ∡:  y

3rd ∡:  z

Equations we can create from data given in problem:

y + z = 5x

z = 5x + 10

We have enough expressions to create an equation:

x + 5x + 5x + 10 = 180

11x = 170

x = 15.5

y = 5(15.5) = 77.25

z = y + 10 = 87.25

What number is smaller number -5 or -15? Explain your answer. Please help college math basic algebra
Goryan [66]
-15 is the smaller number because the further you go into the negatives like -30, -47, -52; youre getting further away from 0 and after 0 are positive numbers so -15 would be the smaller number

"Sketch a possible graph for a negative Quintic polynomial with one real zero." Can anyone explain how this is done? And if poss
Sidana [21]

quintic means degree of 5.

a negative quintic would be: f(x) = -x⁵ <u>+              </u>

an example with one real zero could be: -x⁵ + x³ + x + 3   (see attachment)
