Answer:
angle 1=58
angle 4=122
Step-by-step explanation:
180-122=58
180-58=122
because all straight lines= 180
First set up your two equations:
x + y = 90
x = 2y - 30
Then substitute what x equals in the second equation into the first equation:
(2y -30) + y = 90
Now solve for y:
3y -30 = 90
3y = 120
y = 40
Then use y = 40 and substitute the value for y into one of your original equations and solve for x. I'll choose the first one, but either one will work.
x+ 40 = 90
x = 50
So your solution is x = 50 and y = 40
Answer:
22.50
Step-by-step explanation:
if one mile is 1.50 then just do 1.50*14 which gives you 22.50
