Question

if sin a equal to Cos A minus 10 find the value of a​

Answer 1

Answer:

▶Here's your answer

$\sin(a) = \cos(a) - 10 \\ \\ \cos(90 - a) = \cos(a) - 10 \\ \\ - a - a = - 10 - 90 \\ \\ - 2a = - 100 \\ \\ a = 50$

Hope it helps ✌

Answer 2

Answer:

GIVEN. SINA = COS(A -10 )..............1

SIN A = COS (90-A)

THEREFORE

PUTTING IN 1

COS(90-A)= COS (A -10)

90-A=A-10

2A=100

A=50 ANSWER
