Answer:

The measure of the third angle is 75 degrees.

Step-by-step explanation:

We know that the total angles of a triangle must equal 180 degrees. If we know two of the angles, we must add them together, then subtract them from 180. 45 + 60 = 105, 180 - 105 = 75. The measure of the third angle is 75 degrees.

Answer:

x=75

Step-by-step explanation:

First of all, remember that a triangle always equals 180 degrees.

So, the equation would be 45+60+x= 180.

Step 1- Add common multiples.

(45+60)+x= 180

105+x= 180

Step 2- Subtract to both sides.

105+x= 180

-105      -105

x= 75
