Answer:
126 degrees
Step-by-step explanation:
Triangle: y = 180 - (5x + 4x)
Straight angle: y = 180 - (4x + 30)
180 - (5x + 4x) = 180 - (4x + 30)
5x + 4x = 4x + 30
5x = 30
x = 6
Angle:
y = 180 - (5x + 4x)
y = 180 - 9x
y = 180 - 9(6)
y = 126
V = value
t = time ( number of years)
so V=1045 - 95t
to find the number of years to reach 0
0=1045-95t
1045=95t
t=11 years
Okay, this is a written proof so what you have to do is list the steps. I am going to try my best to solve this problem...
