<h3>Given</h3>
regular polygons with 5, 16, and 12 sides
<h3>Find</h3>
the measures of each interior and exterior angle
<h3>Solution</h3>
The sum of exterior angles is 360° for any convex polygon. For a regular n-agon, the measure of an exterior angle is 360°/n. The corresponding interior angle is its supplement.
(a) pentagon. Exterior angle: 72°; Interior angle: 108°.
(b) 16-gon. Exterior angle: 22.5°; Interior angle: 157.5°.
(c) dodecagon. Exterior angle: 30°; Interior angle: 150°.
Answer:
C. A square is a rhombus
Step-by-step explanation:
A square fulfills all the requirements to become a rhombus:
A. All sides being equal.
B. The diagonals bisected at an angle of 90 degrees
Answer:
No they would not because they are all different angles but if they were all the same numbers than yes so this triangle is a scalene that has no angles that are the same
Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
