Answers

Answer:

The measure of the first angle is 32° and the measure of the second angle is 49°. (h = 32° & c = 49°)

Step-by-step explanation:

For the first triangle, we know that when you add up all the angles in a triangle, you'll end up with 180°. Keeping that in mind, all you have to do to find the third angle is add up the two we already know and subtract it from 180°.

1. 58° + 90° = 148°  -->  I know that the second angle is 90° because it's a right

180° - 148° = 32°           triangle.

2. 82° + 49° = 131°

180° - 131° = 49°

Hope this helps,

Hedgehog68

Angle H is 32, Angle C is 49

A triangle equals to 180 degrees in total, the first triangle gave me 58 and 90 as starting angles so I subtracted those 2 from 180 and got 32
The second triangle gave me 82 and 49 so I subtracted those 2 from 180 and got 49
