Answer:
x = 2.75
Step-by-step explanation:
3^2 +4^2 =c^2
9+16=25
5^2 =25
5-2.25= 2.75
Answer:
8 times 2a - 8 times 7
Step-by-step explanation:
The answer: 16a - 56
Answer:
67.5 - 67.5 - 45 °
Step-by-step explanation:
Sum of INTERIOR angles of a polygon
(n-2) * 180 <====<u>ya just have to remember/know this !</u>
n is the number of sides n = 8 in this case
(8-2)*180 = 1080 ° < === this is the SUM of the 8 interior angles
EACH interior angle is then 1080 / 8 = 135 °
you can see from the picture that each of the two outside angles of the green triangle are 1/2 of this = 67.5° each
so the triangle measurements are
67.5 - 67.5 - 45 ( they have to sum to 180 for triangle)
