Step-by-step explanation:
<em><u>The prism is attached.</u></em>
<em><u></u></em>
The volume formula is:
Where
V is volume
B is area of base
h is height of prism
Now, solving for "h", gives us:
Looking at the prism, it is given:
V = 175
B = 35
Substituting, we get the height:
The height is 5 ft
Answer:
yes
Step-by-step explanation:
Yes this triangle is right angled and can be justified using the Pythagorean theorem. The theorem states that: . Substitute using the given values:
(9^2)+(12^2)=15^2
81 + 144 = 255
255 = 255.
It satisfies the theorem therefore it is a right angle triangle.
