First you do 180 - 165 to find the exterior angle, because all exterior angles equal 360 on a regular polygon. You get 15, so then you just do 360 ÷ 15 which is 24, which is your answer. I hope this helps!

Explanation:
The figure will be a rectangle only if the angles between adjacent congruent sides are 90°.

Attached is an example of a quadrilateral with 3 congruent sides. It is not a rectangle, but could be an isosceles trapezoid if the top and bottom sides were parallel. It would be a parallelogram (rhombus) if opposite congruent sides were parallel.
Answer:
13) B
14) A
15) B
16) 77% > 60%
17) 1.3 < 1
= 1.6
18) .8 = 80% > 8%
19) B
20) A
21) A
= 0.4 , 0.42, 50%
Step-by-step explanation:
Answer:
smallest angle measure 39 degrees
Step-by-step explanation:
the sum of the three interior angles in a triangle is always 180°
x= smallest
x +x+24 + 2x = 180
4x +24 = 180
4x = 156
x = 39
