Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
=
=
( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13
A is the answer 7th graders are not likely
Volume is L x W x H
8 x 10 x 3 = 240 cubic units
Answer:
x = 40
y = 15
Step-by-step explanation:
Given is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60°.
Therefore,
(x + 20)° = 60°
x + 20 = 60
x = 60 - 20
x = 40
4y = 60
y = 60/4
y = 15
