Answer:

7.7 cm

Explanation:

You need to use trig ratios

this one needs the sin as we been to find the opposite side with the hypontenuse

9 x sin(45) = PQ = 7.65813172081

PQ = 7.7

Answer:

9 sqrt(2) /2 = PQ

Explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 45 = PQ = 9

9 sin 45 = PQ

9 sqrt(2) /2 = PQ
