Answer:
I believe the answer is as follows:
Step-by-step explanation:
Interior angles: p, q, r
Exterior angles: t, s, v, u
okay so
117° + angle a = 180° (supplementary angle)
angle a = 180 - 117
= 63°
then angle a + angle b + 81° = 180° ( angle sum property)
so... 63° + angle b + 81° = 180
144 + angle b = 180°
angle b = 180 - 144
= 36°
hope this helps.

We know that,
diameter is twice the radius, I.e d = 2r
Now d = 2(8)ft = 16 feet
