Answer:

F

Step-by-step explanation:

This is F. This is because, when both sides of the triangle is 42, and when you add it up it is 84. Now 84 + x will be the answer. The total sum of all of the measurements of a triangle is ALWAYS 180! So, the answer is the first option F.

Hope this helps!!

The abase angles of an isosceles triangle must always be the same so if you add them together, making 84 you have to subtract it from 180 which is the total sum of angles of the triangle so 180-84=96 sot he missing angle is 96
