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:
