help me >.<

Answer 1

180-105=75
75+24=99
180-99=81

Answer 2

The angle right next to the 105-degree angle is 75 degrees becuase the two angles lie on a straight line. so 180-105 = 75.

So you have two angles in the triangle you know, the 75-degree angle and the given 24-degree angle. You can now find x, as the sum of all 3 angles of a triangle equals 180 degrees.
