In a triangle, the three interior angles always add to 180°
x = 180 - 101 - 28 = 51°
They are just basically saying just to subtract the highest point from the lowest point.
You just subtract 6,773 yards and 87 yards
The answer is: 6,686 yards
(trying to isolate/get x by itself in the equation)
5(x + 6) = 50 Distributive property [distribute 5 into (x + 6)]
5x + 30 = 50 Subtraction [subtract 30 on both sides of the equation]
5x = 20 Division [divide 5 on both sides]
x = 4
Subtraction then division, the 2nd option
Here they are:
Sue = (18-x)/2
Tony = (18+x)/2
