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

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

C 27°

Step-by-step explanation:

Total angle in a triangle: 180

180 = 62 + 91 + X

180 = 153 + X

X = 180 - 153

X = 27°

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the
