Answer:
X=50
Explanation:
Since a line equals 180 ( even if it's bisected- meaning there is a line through it ) and you know one side is 113, you subtract 113 from 180 to find the other side ----> 180-113= 67. so now you know the small right angle in the triangle is 67°
Then since a triangle also always equals 180° and now you know that one angle is 63 and the other is 67, you just subtract those from 180 to find the third angle ( which is x) -----> 180-67-63=50
So x=50
Hopefully this wasn't too confusing...
