1. Answer:</h2>
A right triangles is a triangle having a 90 degree side. According to the figure, the sides of this triangle are expressed in inches. Therefore, we can find the missing sides and angles as follows:
<u>m∠B:</u>
The sum of the three interior angles of any triangle is 180°, therefore:
<u>CA and AB:</u>
We must use the law of sines as follows:

2. Answer:</h2>
According to the figure, the sides of this triangle are expressed in meters. Therefore, we can find the missing sides and angles as follows:
<u>m∠A:</u>
The sum of the three interior angles of any triangle is 180°, therefore:
<u>CA and CB:</u>
We must use the law of sines as follows:

Answer:
Yes. parallel lines are known to have the same slope, but perpendicular lines will always have negative-reciprocal slopes.
In the comment of the other answer, you said that the rectangle is 24 x 18 ft.
First, we have to find out how many square feet that is, and then we can convert it to square yards.
The area of a rectangle is the length multiplied by the width.
A = l x w
A = 24 x 18
A = 432 square feet
To find out how many square yards that is, we divide it by 3, because 1 yard is 3 feet.
432 ÷ 3 = 144
The area of a 24x18ft rectangle is 144 square yards.
