Question

When solving for the measure of an angle in a right triangle, what information do you need

Answer 1

The angles you know, added together subtracted from 180

180 - (Right angle + angle you know)

OR

the other angles as the person said

Explanation:

Lets say a triangle has a right angle, an angle of 55 degrees, and an unknown angle. We want to find the angle of the unknown angle (excuse my wording)

Since we know that right angles are always 90 degrees, we can add that with the 55 degrees of the other angle that we know.

90 + 55 = 145.

Since triangles have a total angle of 180 degrees, we subtract 180 - 145.

180 - 145 = 35

So the answer is 35.

I hope this helped :)
