how do i find the volume of a triangular prism that has a 10m width a 4m base and a 8m hight don't worry about the T

Alecsey [184]

The volume of a triangular prism is equal to :
area of the base x height

the area of the base :
$10 \times 4 \div 2 = 40 \div 2 = 20$

so the volume is
$20 \times 8 = 160$

the answer is 160m^3

good luck

Find the length of GI in the triangle below. Show your work.

love history [14]

Answer:

<u>The length of GI is 90.06 units</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

GH = 60 units

HI = 42 units

∠H = 123°

2. Using the Law of Cosines, we can find the length of GI, this way:

GI² = GH² + HI² - 2 * GH * HI * cos ∠H

Replacing with the real values:

GI² = 60² + 42² - 2 * 60 * 42 * cos ∠123°

GI² = 3,600 + 1,764 - 2 * 60 * 42 * -0.545

GI² = 3,600 + 1,764 + 2,746.8

GI² = 8,110.8

<u>GI = √ 8,110.8 = 90.06 units</u>
