Question

Which angles equal 912

A: Angles t & v
B: angles s & u
C: angles u & v
D: angles s & t

Answer 1

Explanation:

Answer a

Answer 2

Option A

Explanation:

we know that

tan(A)=sin(A)/cos(A)

Solve for sin(A)

sin(A)=tan(A)cos(A)

we have

tan(A)=\frac{9}{12}

cos(A)=\frac{12}{15}

substitute

sin(A)=\frac{9}{12}(\frac{12}{15})

sin(A)=\frac{9}{15}
