Answer:
x = 23
Obtuse scalane triangle
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
110+35+x+12 = 180
157 + x = 180 subtract x from both sides
x = 23
The given triangle is an obtuse scalane because it has no eqaual side lengths or angles measurment.

The volume of the solid generated by revolving the region bounded by the given curve and lines about the x-axis is V = 8π/3
<h3>What is the Volume of a solid?</h3>
The volume of a solid, given by the function f(x), over an interval between a and b, is given by:
To find the area, integrate around that area. We're revolving around the x-axis so the area will be a circle;
V = ∫A(x)dx = ∫(πr²)dr
Then we subtract them from each others.
∫(πr₂² - πr₁²)dr
Now substitute the value and integrate;
∫(π(2)² - π(2x)²)dr
∫(4π - 4πx²)dr
4π∫(1 - x²)dr
Now integrate from 0 to 1 since that's where our boundary is.
V = 4π∫(1 - x²)dr = 8π/3
Therefore, The volume of the solid generated by revolving the region bounded by the given curve and lines about the x-axis is V = 8π/3
