First find the measure of x.
12x + 3x = 90
15x = 90
x = 6
Plug in x into ∠PVQ, which is 12x.
12(6) = 72
m∠PVQ = 72°

Answer:
24 cm
Step-by-step explanation:
Assuming that the triangles are similar,
then the ratio of their sides must be the same.
in this case you are dealing with 2 longest sides and the 2 shortest sides.
We are asked to find the y (the length of the shortest side of the blue triangle)
because they are similar, we can form a ratio with their sides:
Purple Long Side / Blue Long Side = Purple Short Side / Purple Long side
100 / 80 = 30 / y
100y = (30)(80)
y = (30)(80) / 100
y = 24 cm
