Let's make a reference triangle with the x and y axes as the legs of the right triangle. The hypotenuse is the slope where the angle of elevation is based. Given an angle of elevation of 53 degrees, the remaining angle is 37 degrees. Use sine law to calculate for the hypotenuse:
(sin 53/x) = (sin 37/y) = (sin 90/z)
solve for x, y and z. The slope is y/x
x + 77 = 3(x - 6)
x + 77 = 3x - 18
x + 77 + 18 = 3x - 18 + 18
x + 95 = 3x
x + 95 - x = 3x - x
95 = 2x
x = 95/2
x = 47.5
Answer: 1,400 calories
Bianca jogged 1.25 miles per day for 8 days. so 1.25*8 would equal 10 miles.
Since she jogged 10 miles and burned 140 calories per mile, if we multiply 10*140, we would get 1,400.
So last month, she lost 1,400 calories.
