What Is The Surface Area Of this triangular prism? The Base Of Each Triangle 42m And the height of the triangular base is 20m. (
ehidna [41]

Answer:

The surface area is 2,440\ m^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The surface area of a triangular prism is equal to

SA=2B+PH

where

B is the area of the triangular base

P is the perimeter of the triangular face

H is the height of the prism

<em>Find the area of the base B</em>

B=\frac{1}{2}(42)(20)=420\ m^{2}

<em>Find the perimeter of the base P</em>

P=(42+29+29)=100\ m

we have

H=16\ m

substitute the values

The surface area is

SA=2(420)+100(16)=2,440\ m^{2}

Through: (1,5), perp. to y=-1/10x + 3<br> pls help
Sedbober [7]
First to get the equation you knew to understand one thing about perpendicular lines. The slope of the line is the opposite reciprocal of the perpendicular lines or the new slope is m = 10.

Then you use the formula
y = mx + b
you plug in your values from the point and the new slope.
(1,5) with new slope m
5= 10(1)+b
5-10=b
-5 = b
then make your new equation
y = 10x -5
that's your line that goes through point (1,5) and is perpendicular to the line given
