Question

What do the angles of a triangle add up to? If 2 angles are 34 and 18, what is the third angle?

Answer 1

Answer:

The third angle is 128 degrees

Step-by-step explanation:

The interior angles of a triangle add up to 180 degrees, therefore we can set up the equation x+34+18=180 to find the missing angle. Solving the equation gets us x=128

Answer 2

Answer:

Angles of a triangle add up to 180 degrees. The third angle would be 128 degrees.

Step-by-step explanation:

34 + 18 = 52

180 - 52 = 128
