Question

From the given figure if A = , find sin, cot and tan + cot.

Answer 1

Answer:

i don't know what is the answer

Answer 2

Answer:

by PT theorem

AC²=AB²+BC²

100=36+BC²

BC²=100-36

BC²=64

BC=8

thus

sin = 8/10

cos = 6/10

cot= cos/sin = 8/6

tan = sin/cos = 6/8

tan + cot= 6/8 + 8/6

tan + cot= 100/48= 25/12

tan+cot=25/12
