Answer:
20 degrees
Step-by-step explanation:
First, you need to figure out what x is by adding all of your information.
(5x-5)+(14x)+90=180
19x+85=180
19x=95
x=5
Then plug it into 5x-5 and you will get 20 degrees
c = 81
(k-9)(k-9)
k²-18k +81
Gradient = -3
• Parallel lines have the same gradient, therefore gradient, m is -3
• At point (0, -4)
y intercept is -4
