Answer:
21.25
Step-by-step explanation:
so what I did was i x 8 and 1/2 by 2.50
2.161616 = 2.161616/1 =21. 61616/10 = 216.1616/100 = 2161.616/1,000
= 21616.16/10,000 = 216161.6/100,000 = 2161616/1,000,000
As a mixed number = 2(161616/100,000)
Angle C equals 63
Add angle 17 plus 100 and the subtract the answer from 180. Because a triangles are always 180 degrees
4,200+525(5×12)
4,200+525(60)=
4,200+31,500=35,700
