Answer:
x = 16
Step-by-step explanation:
the labeled angles are all exterior
the sum of all exterior angles always equals 360 degrees
9x+1 + 5x+12 + 10x-37 = 360
24x - 24 = 360
24x = 384
x = 16
Answer:
Step-by-step explanation:
The perpendicular is equal to 6. That's because the left triangle's missing angle is 180 - 45 -90 = 45
The angle in the right triangle is given as 52.
The cos(52) = adjacent side (which we just found to be 6) / y
Multiply both sides by y
y cos(52) = 6
cos(52) = 0.6157
Divide by sides by cos(52)
y = 6 / cos(52)
y = 6 / 0.6157
y = 9.76
