I think it is the first option. hope this helps :)
Hello!
Since the shape has 6 points it is a hexagon
The sum of the angles in a hexagon add to 720
You add all the angles you know
102 + 133 + 117 + 170 + 90 = 612
Subtract this from 720 to find b
720 - 612 = 108
The answer is B) 108°
Hope this helps!
Answer:
Below in bold
Step.-by-step explanation:
It consists of 5 isosceles triangles of equal sides 4 cm and vertex angles 360 / 5
= 72 degrees.
Area of 1 triangle = 1/2 * 4^2 *sin 72
Area of the whole pentagon = 5 * 1/2 *4^2 * sin 72
= 38.04 cm^2.
Answer:
C = 5/2 - 6/7
