Question

Complete the following activity to find cos 0;if sin 0=7/25

Answer 1

Answer:

cos 0 = 24/25

Step-by-step explanation:

sin² 0 + cos² 0 = 1

49/625 +cos² 0 = 625/625

cos 0 = √(576/625) = 24/25

Answer 2

Answer:

perpendicular=7

hypotaneous=25

sin theta= p/h

h²= p²+ b²

(25)²=7²+ b²

625-49=b²

b²=576

b=✓576

b=24

cos theta=b/h

cos theta=24/25
