Answer 2

Answer:

49/64 and 49/64

Step-by-step explanation:

cot∅ = 7/8

cot∅ = b/p

hypotenuse² = b² + p²

h² = 7k² + 8k²

h² = 49k²+64k²

h² = 113k²

h  = √113k

sin∅= p/h = 8 / √113

cos∅ = b/h = 7/ √113

(1 + sin∅)(1-sin∅) = 1-sin²∅

(1-cos²∅)(1+cos²∅) = 1 - cos²∅

1-sin²∅/1-cos²∅

1-sin²∅ = 1-(8/√113)²= 113-64/ 113 = 49/113  -1

1-(7/√113) = 113-49/ 113 = 64/ 113  -2

divide 1 and 2

49/113 / 64/113 = 49/64

2 . cot²∅

cot∅= 7/8

by squaring cot∅ we get

(7/8)² = 49/ 64

i hope this helps !!
