To find the length of the altitude, we have to use the ratios of the similar sides.
Let the length of altitude=x
Ratio of sides:

So length of altitude is 9 cm.
Answer: 9 cm
Answer:65.6
Step-by-step explanation:
So $0.25 per yard
16.4/$0.25=65.6
Answer:
12(4+3)
Step-by-step explanation:
Length = width +6
L * (L - 6) = 135
L^2 - 6L = 135
L^2 - 6L -135 = 0
Length = 15
Width = 9
Answer:
132 degrees
Step-by-step explanation:
these angles are Alternate interior angles so angle A is congruent to angle B.
5x-18 = 3x+42
-3x -3x
2x-18 = 42
+18 +18
2x = 60
÷2 ÷2
x=30
A=5(30) -18
= 150-18
= 132 degrees
