there is a right angle

Answer 2

The angle sum property of a triangle:

The total measure of the three angles of a triangle is 180°

`\rm\large\rightarrow \: \: x \: + \: 55 \degree \: + \: 90 \degree \: = \: 180 \degree`

`\rm\large\rightarrow \: \: x \: + \: 145 \degree \: = \: 180 \degree`

`\rm\large\rightarrow \: \: x \: = \: 180 \degree \: - \: \: 145 \degree`

`\rm\large\rightarrow \: \: x \: = \: 35 \degree`
