Question

Work out the size of angle x.

Answer 1

Answer:
13

Step-by-step explanation:
85 is vertical
98 vertical
180 - 98 = 82
82 vertical
85 + 82 = 167
180 - 167 = 13

Answer 2

13 degrees.

Step-by-step explanation:

First we calculate the other 2 angles of the triangle of which < x is a part.

The bottom angle = 85 (vertical angles are equal).

The top one = 180 - 98 = 82. ( corresponding and adjacent angles).

So angle x = 180 - (85 + 82).

= 180 - 167

= 13 degrees.
