Answer:
b
Step-by-step explanation:
The inscribed angle 36°m is half the measure of its intercepted arc, that is
b = 2 × 36 = 72
c = 360 - (108 + 72) = 360 - 180 = 180 ( total sum of arcs in a circle )
The angle between a tangent and the radius of a circle at the point of contact is 90° , then
d = 90
Thus b = 72, c = 180, d = 90 → b
If it's in a fraction you want it it's 207/50 irregular
And 4 7/50 as a mixed fraction
1 inch square base
4 triangular faces
72
I can only answer the first two, sorry.
