M<STR = 180 - 8x  degrees
also m < SRT = 180-8x ( because side RS = side ST, so isosceles triangle)
So 
7x - 54 + 180 - 8x = 8x  (ext. angle of triangle =sum of opposite internal angles)

7x - 8x - 8x = -180 + 54 = -126
-9x = -126
x = 14 answer

The sum of the measures of the angles of a triangle is 180 degrees.

Angles STU and STR are supplementary angles.
Angles R and STR are congruent.

m<STU + m<STR = 180

8x + m<STR = 180

m<STR = 180 - 8x

m<R = m<STR = 180 - 8x

m<RST + m<R + m<STR = 180

7x - 54 + 180 - 8x + 180 - 8x = 180

-9x + 360 = 180

-9x = -126

x = 14

The base of a solid is bounded by the curve y = sqrt (x+1) the x-axis and the line x = 1. the cross sections, taken perpendicula
Andrei [34K]

See attached for a sketch of some of the cross sections.

Each cross section has area equal to the square of the side length, which in turn is the vertical distance between the curve y = √(x + 1) and the x-axis (i.e. the distance between them that is parallel to the y-axis). This distance will be √(x + 1).

If the thickness of each cross section is ∆x, then the volume of each cross section is

∆V = (√(x + 1))² ∆x = (x + 1) ∆x

As we let ∆x approach 0 and take infinitely many such cross sections, the total volume of the solid is given by the definite integral,

\displaystyle \int_{-1}^1 (x+1) \, dx = \left(\frac{x^2}2 + x\right) \bigg|_{-1}^1 = \boxed{2} ~~~~ (B)
