Answer:
Incident ray, the reflection ray and the normal to thereflection surface at the point of the incidence lie in the same plane
Y/-2 + 5 = 13
y/-2 = 13 - 5 = 8
y = -2(8) = -16
y = -16
180 degrees in a triangle. subtract the 2 know angles to get the third.
180-39-24=117
21,000-600 = 20,400
20,400/3400 = 6
t = 6
21,000=3,400(6)+600
21,000=20,400+600
21,000=21,000
34.00
*6
__
204.00
3,400*6=20,400
