First you need the size of an angle QPR = B = 180° - 123°
Lenght of QP = 10cm
QR = x
QP = r
x² = r² + r² - 2r² × cosB
1/6y - 4 = -7
1/6y = -7 + 4
1/6y = -3
1 = -18y
-18y = 1
answer
y = -1/18
Just take a calculator and divide 4 by 10 exactly how you see it. Or just divide it like you normally would any number on paper. 0.4 is your answer.
