To find the volume of a triangular pyramid, the formula is:
So we start by finding the area of the base, which is in the shape of a right triangle in this case.
The area of a right triangle is equal to 1/2 x base x height.
We use this area to find the volume.
The volume of the triangular pyramid is 30 cubic feet.
-5x⁽²⁺³ˣ) - 2x(x-4)
Let's seperate the equation, and do the first half first.
-5x ⁽²⁺³ˣ⁾
Multiply -5x with 2.
Then, multiply 3x with -5x.
That gives us: -10x - 15x²
Now, let's do the second half.
2x(x-4)
2x²-8x
Now, let's put them together.
(-10x-15x²) - (2x²-8x)
Add like terms.
(-2x² - 15x²) - (-8x - 10x)
Simplify.
-17x² - (-18x)
-17x² + 18x
~Hope I helped!~
answer:
x=78
since it's an isosceles triangle base angles are equal sum of all angles in traingle is 180 so
24+x+x=180
2x=156
x=78
hope.. this helped <3!!!
