Question

2 triangles measure 55 and 20 what is the measure of the third angle

Answer 1

third triangle=105 degrees

Explanation:

Three angles of a triangle always add up to 180. Therefore the equation is 55+20+x=180. Solving for x we get x= 105

Answer 2

x = 105

Explanation:

The angles of a triangle add to 180 degrees

Let x be the third angle

55+20 +x =180

75 +x = 180

x = 180-75

x = 105
