Question

What the value of x?

Answer 1

75°

Explanation:

Angles in a triangle add up to 180°, so 42° + 63° + x° = 180°.

This can be simplified to 105° + x° = 180°.

Finally, solve for x: x° = 180° - 105° = 75°

Hope this helps!

Answer 2

X=75

Explanation:

All angles of a triangle = 180

We are given 63 and 42

So we'll subtract 63 and 42 from 180

180-63=117

117-42=75

x=75
