m∠PQR=82º

1) According to the properties of a Rhombus, the line segment QS bisects the angle ∠PQR into two congruent angles ∠PQT and ∠RQT

So we can write

∠PQT = ∠RQT

Let's find the value of x:

4x-27= 2x +7

4x -2x = 7 +27

2x = 34

x= 17

2) So m∠PQR is going to be the sum of m∠PQT and m∠RQT

m∠PQR=m∠PQT +m∠RQT

m∠PQR = 4x -27 +2x +7 Plug into that the value for x=17

m∠PQR =4(17) -27 + 2(17) +7

m∠PQR =68-27+34+7

m∠PQR=82º

3) So the answer is m∠PQR=82º
