Answer:
29
Step-by-step explanation:
The right triangle is isosceles triangle so we have the left angle of it is:
180-64=116
116÷2=58
Then start to calculate the left triangle angles:
180-58 = 122
180-122 = 58
58÷2 = 29
Note that
and
.
From the unit circle, we can check that
and
have the same value, but opposite signs, that is:
.
Thus,
.
Note that
is the x-coordinate of the lowest point on the unit circle, that is (0, -1). Thus
