(never mind solved it myself, the answer is a 0.6)

in pqr, what is sin q written as a decimal?

a) 0.6

b) 0.75

c) 0.8

d) 1.667

Option A) 0.6

Step-by-step explanation:

we know that

In the right triangle PQR

The function sine of angle Q is equal to divide the opposite side to angle Q by the hypotenuse

substitute the values

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
