A triangle has angle measurements of 62 degrees and 91 degrees. What is the measurement of the third angle?

A. 153 degrees
B. 180 degrees
C. 27 degrees
D. 29 degrees

Answer :

Answer:

C 27 degrees

Step-by-step explanation:

The sum of the angles of a triangle add to 180. Let x be the third angle

62+ 91 +x = 180

Combine like terms

153+x = 180

Subtract 153 from each side

153+x-153 = 180-153

x =27

Answer:

C 27°

Step-by-step explanation:

Total angle in a triangle: 180

180 = 62 + 91 + X

180 = 153 + X

X = 180 - 153

X = 27°
