Because a triangle is 180 degrees, and you already have a right angle that leaves 90 degrees for the rest of the angles.
So, (2x) + (x+15) = 90
Combine like terms.
3x + 15 = 90
Subtract 15 from 90.
3x = 75
Divide.
75/3, so x = 25.

Answer:
Volume of hemisphere is equals to 1071.78666 cubic unit
Step-by-step explanation:
Given: radius of hemisphere=8 unit
A hemisphere is a 3-dimensional object that is half of a sphere.
Volume of hemisphere is equal to two thirds multiplied by pi multiplied by radius to the power 3.
<u>Formula:</u> Volume of hemisphere(V) where r is the radius of the hemisphere and the value of pi is constant i.e,
Now, substitute the value of r to find the volume of hemisphere,
Volume of hemisphere(V)=
∴ =1,071.78666 cubic unit.
