Answer:
83.5
Step-by-step explanation:

Answer:
x = 
Step-by-step explanation:
Given
A =
xy
Multiply both sides by 2 to clear the fraction
2A = xy ( divide both sides by y )
= x
Answer:
m∠QPR = 25°.
Step-by-step explanation:
If m∠QPR = 9x + 16°, substitute in 1 for 'x':. 9(1) + 16 = 9 + 16 = 25°
X = 25.5 mm.
Using the similarity statement given, that ΔABC ~ ΔDEF, we set up a proportion:
8.5/x = 4/12
Cross multiply:
4*x = 8.5*12
4x = 102
Divide both sides by 4:
4x/4 = 102/4
x = 25.5
