Question

Two angles of a triangle measure 55 and 20 what is the measure of the third angle of the triangle

Answer 1

the third measure is
`105`°

Explanation:

All measures of a triangle add up to 180°

`A+ B + C = 180`

`20 + 55 + C = 180`

`75 + C = 180`

`C = 105`°

Answer 2

105 degrees

Explanation:

well if we take a look at this

we know for sure that every triangle must have a total angle measurement of 180 degrees

so if we take the information we have and we add those together

55 + 20

that will give us

75

then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it

180-75

giving us 105 degrees as the third measurement of the angle in the triangle
