Question

What is the consine of angle B?

a. 8/17

b.15/17

c. 17/8
d. 8/15


What is the tarent of angle A?

a. 8/15
b. 15/8
c. 17/8
d. 8/17

Answer 1

COSB= 8/17

TANA=8/15

Explanation:

`for \: the \: cosine \: of \: angle \: b \\ we \: should \: note \: that \: cosb = (adjacent)/(hypothenus) \\ from \: the \: shape \: cosb = (8)/(17) \\ for \: the \: tangent \: of \: angle \: a \\ tan \: a = (opposite)/(adjacent) \\ tan \: a \: = (8)/(15)`
