Question

The measures of the angles of a triangle areshown in the figure below. Solve for x.111o 42o xo

Answer 1

The Solution.

The sum of angles in a triangle is 180 degrees.

Hence,

`x+42+111=180`

Collecting the like terms, we get

`x+153=180`
`x=180-153`
`x=27^o`

Hence, the correct answer is 27 degrees.
