Answer:
sometimes, if their average angle is over 45 degrees
never are 2 obtuse angles summing to 180 degrees
always. two 90 degree angles always sum to 180 which is a straight line
Answer:
x = 84
Step-by-step explanation:
The two angles form a line
A line is 180 degrees
x+11 +85 = 180
Combine like terms
x+96 = 180
Subtract 96 from each side
x+96-96 = 180-96
x = 84
To do this you equate the two and use x for hours.
So your equation looks like this: 100+15x=75+17x. Now move like terms to get 25=2x. The job will be 12.5 hours long to cost the same.
