Answer:
I thunk the answer is 26.
Step-by-step explanation:
Equation; 90 + 64 = 154.
180 - 154 = 26.
64 is obvious. It tells you that we have a 64 degree angle.
90 is also pretty obvious. It doesn't exactly say 90, but the square on the angle tells you its 90. You may only have 180 degrees. So with that, you do 180 -(90+64).
