maka
180 = sudut PQS + susut SQR
180 = 5x + 4x + 9
180 = 9x + 9
180-9 = 9x + 9 - 9
171 = 9x
1/9 x 171 = 1/9 x 9x
19 = x
sudut SQR maka (4x+9) = (4 × 19) + 9 = 76 + 9 = 85 derajat
5x + (4x + 9) = 180
5x + 4x + 9 = 180
9x + 9 = 180
9x = 180 - 9
x = 171/9
x = 19
Pelurus sudut SQR = PQR
= 5x
= 5.19
= 95 derajat
