The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 45 degrees, and the

Helen [10]

Answer:

67.5 degrees

Step-by-step explanation:

The first angle is 45 and the second angle is x and the third angle is x (the second and third are equal)

We know the 3 angles of a triangle add to 180 degrees

45+x+x = 180

Combine like terms

45+2x=180

Subtract 45 from each side

45-45 +2x = 180-45

2x= 135

Divide by 2

on each side

2x/2 =135/2

x = 67.5
