Answer:
77*
First we are going to take our given number, 25* and 78* and add them together.
25* + 78* = 103*
And subtract our answer, 103*, from 180*.
180* - 103* = 77*
77* is our missing angle. To prove it, we add angle measures a, b, and c, to make the number 180*
25* + 78* + 77* = 180*
Another way to write it is . . .
180* - (A + B) = C

I think pencil and paper would be the best method
Answer:
Step-by-step explanation:
<u>The circle has a circumference:</u>
This the is arc of full length θ = 360°
<u>Each degree of arc length is:</u>
- s = 2πr*θ / 360 = πrθ / 180
<u>We have:</u>
<u>The arc length is:</u>
- s = π*6*25/180 = (5/6)π inches terms of π
<u>The same arc is:</u>
- s = (5/6)*3.14 = 2.62 inches (rounded)
