A triangle is placed in a semicircle with a radius of 5 yd, as shown below. Find the area of the shaded region.

Svetradugi [14.3K]

Answer:

14.25 yd^2

Step-by-step explanation:

The triangle area is given by the formula ...

A = 1/2bh

Here, the base is 10 yd, and the height is 5 yd, so ...

triangle area = (1/2)(10 yd)(5 yd) = (5 yd)^2 = 25 yd^2

The semicircle is half the area of a circle with radius 5 yd, so its area is ...

semicircle area = (1/2)π(5 yd)^2 = 12.5π yd^2 ≈ 39.25 yd^2

The shaded region is the difference between these areas:

shaded area = 39.25 yd^2 -25 yd^2 = 14.25 yd^2

In the figure shown, r || s. If the measure of ∠ 2 = 146°, what is the measure of ∠ 7

borishaifa [10]

Answer:

34°

Step-by-step explanation:

1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.

2. (Solving for ∠1)

$146 + x = 180$
$146 + x - 146 = 180 - 146$
$x = 34$

3. Now, since we know ∠1 = ∠7, ∠7 = 34°.
