Step-by-step explanation:
In a right angle triangle one angle is 90°
w.k.t sum of angles in a triangle is 180°
thus, 2x+15+x+90°=180°
3x+105°=180°
3x=75°
x= 75/3=25°
Hope this helps you.
The area of a rectangular prism would be A=2(wl+hl+hw)

I hope this makes sense, if not please feel free to let me know and I'll explain it.
The area of the resulting figure will be given by:
∫f(x)dx
f(x)=13/2x^3
thus
∫f(x)dx=13/2∫x³dx=13/8[x^4]
integrating over the inerval
13/8(12^4)-13/8(5^4)
=32680+3/8 sq. units
=
4/6
4/6 = 2/3
4/6 = 8/12
Answer : 2/3 and 8/12
