Answer: C) Equilateral Triangles

Any two triangles are similar if they have the same corresponding angles. In the case of two equilateral triangles, they both have 3 sets of 60 degree angles. So the angles pair up and we can prove them to be similar using the Angle Angle (AA) Similarity theorem. 

This trick only works with triangles. It partially works with rectangles; however, we would need to be sure that the corresponding sides were proportional as well. There isn't a 100% guarantee that any two rectangles are similar.

Greeley [361]

(a) The integral is equal to the area of the triangle; it has height 20 and base 10, so the area is 20*10/2 = 100.

(b) The integral is equal to the area of the semicircle with radius 10. It's also under the horizontal axis, so the area is negative. The semicircle has area \frac{\pi10^2}2=50\pi, so the integral is -50π.

(c) First compute

\displaystyle\int_{30}^{35}g(x)\,\mathrm dx

which is the area of the triangle on the right. It has height and base 5, so its area is 25/2.

Then split up the desired integral as

\displaystyle\int_0^{35}g(x)\,\mathrm dx=\int_0^{10}g(x)\,\mathrm dx+\int_{10}^{30}g(x)\,\mathrm dx+\int_{30}^{35}g(x)\,\mathrm dx

and plug in the integral values you know:

\displaystyle\int_0^{35}g(x)\,\mathrm dx=100-50\pi+\frac{25}2=\frac{225}2-50\pi
