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
Answer:
y = 14
Step-by-step explanation:
y ∝ 
=> y =
-------------(1)
<em><u>Where k is the constant of proportionality</u></em>
Now,
x = 7, y = 4
<em>Putting in (1)</em>
4 = 
So,
=> k = 28
Now y = ? when x = 2
<em>Putting x and k in (i)</em>
y = 
y = 14
