Answer:

y=57, x=77

Step-by-step explanation:

The line that creates x-3 is parrelell to the line that makes 74 degrees

You know that x-3=74

When you simplify you get x=77

Now that you know that x-3=74 you can add all the angles to 180 because they are a supplementary angle

74+41+(y+8)=180, then simplify

115+y+8=180, simplify more

123+y=180

y=57

Goryan [66]

Answer:

The volume of the triangular prism is $V=72\ cm^3$

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

$V=BL$

where

B is the area of the triangular face

L is the length of the prism

step 1

Find the area of the triangular face

The area of a triangle is equal to

$B=\frac{1}{2} bh$

we have

$b=3\ cm\\h=4\ cm$

substitute

$B=\frac{1}{2}(3)(4)=6\ cm^2$

step 2

Find the volume

we have

$B=6\ cm^2$

$L=12\ cm$

substitute in the formula of volume

$V=6(12)$

$V=72\ cm^3$
