Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
2x-10 + 70+ x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide by 3
3x/3= 90/3
x=30
We want to find angle A
A = 2x-10
=2*30 -10
=60-10
50
∠СXA = ∠BXA + ∠СXB = 30°20' + 40°35' = 70°55'
To find the rate, we have to divide both numbers by 5. So the rate will be $1.592 for 1 pound.
