Answer:
34.4
Step-by-step explanation:
Using Triangle Sum Theory, you see that the triangles are similar. They have the same angle measurements. That means their corresponding sides are proportional.
=
=
Cross multiply
14(27) = 11(PQ)
378 = 11(PQ)
= PQ
PQ = 34.4
40% = 40 / 100 = 0.4
32 is 40% of what
= 32 / 40
= 32 / 0.4
= 80

U can also use this equation to solve it.
32 = 40%x

= 32 = 2/5x
Flib the equation.
2/5x = 32
Multipy both sides by 5/2
(5/2) * 2/5x = (5/2) * 32
x = 80.
