Find the volume of the 3-D solid shown below:
KonstantinChe [14]

Check the picture below.

so is really just a thick trapezoid, or namely a trapezoidal prism 5 inches thick.

so if we just get the area of the trapezoidal face and multiply by the thickness, we'd get it's volume

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{parallel~sides}{bases}\\ h=height\\[-0.5em] \hrulefill\\ a = 8\\ b = 13\\ h = 6 \end{cases}\implies A=\cfrac{6(8+13)}{2}\implies A=63 \\\\\\ \stackrel{\textit{area of the trapezoidal prism}}{63\cdot 5\implies \stackrel{in^3}{315}}

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the Quadrilateral. Show your work. ( Plea
oksano4ka [1.4K]

Answer:

  • Shown Below.

Explanation:

opposite angles in a quadrilateral sum up to 180°

total interior angles in a quadrilateral is 360°

solve for x:

x - 2 + x + 2 = 180°

2x = 180°

x = 90°

solve for each angle:

1st

x + 2

90° + 2 = 92°

2nd

x - 2

90° - 2 = 88°

3rd

x - 10

90° - 10° = 80°

4th

360° - 80° - 88° - 92° = 100°

How does graphing help you solve a system of linear equations? i need the answer asap please

Its simply helps you visualizing what part is negative/positive. For inequations (ex: 3x+9>10), its super important to let you know from where to where the equation is, in my example, higher than 10.
