No, because first of all 125 +36 + 24 should equal 180° not 185° because the area of a triangle always has an area of 180. Second, you don't even have to calculate anything because an isosceles triangle has two measures that are the same °∞° Hope this helps!
Answer:
200π

Graph: desmos.com/calculator/pwa9vqzmpy
The region is inside a horizontal parabola y = (5x)^½, starting at its vertex at x=0 and ending at x=5. Cut a thin vertical slice with thickness dx and position x.
Revolving this thin slice about the y-axis, we get a cylindrical shell with radius x, thickness dx, and height 2y. The volume of the shell is:
dV = 2π (x) (2y) (dx)
dV = 4π xy dx
dV = 4π x (5x)^½ dx
dV = 4π√5 (x^³/₂) dx
The total volume is the sum of all the shell volumes from x=0 to x=5.
V = ∫₀⁵ dV
V = ∫₀⁵ 4π√5 (x^³/₂) dx
Evaluating the integral:
V = 4π√5 ∫₀⁵ (x^³/₂) dx
V = 4π√5 (⅖ x^⁵/₂) |₀⁵
V = 4π√5 [(⅖ 5^⁵/₂) − (⅖ 0^⁵/₂)]
V = 200π
The volume of the solid is 200π cubic units.
First you would add any numbers or variables (x) on each sides. So the equation would look like this -5h+12=32. Then you subtract 12 from both side because you are trying to find what H is; thus making the equation look like this, -5h=20. Then you can divide by -5 and the answer would be h=-4. You can plug it back into the equation to make sure it is correct. 10-5(-4)+2=32
10+20+2=32
32=32
It works.

The absolute value of any real number is a non-negative number.
|-25| = -(-25) = 25 > 0
