Step-by-step explanation:
10^2= 100
so b must be 5
Answer:
X=62
Step-by-step explanation:
X=62 because the side where x is and where the other degree is, they are congruent. And since you have to add 12 it would have to be 62 to be equal to 74.
Sum of all the interior angles = (5-2)x180 = 540°
540 - 100 - 120 - 100 - 90 = 130°
So the last unknown angle in the polygon is 130°
Sum of all the adjacent angles on a straight line is 180°
Angle 1 = 180 - 130 = 50°
Answer:
a number less then 6 is the anser so the 1st one
12.5663706144 or yes, 12.57
