Setting up a right triangle, the 100 would be the hypotenuse, the 45 would be the angle of elevation, and you're looking for the opposite side.
Sin 45 = x/100
100sin45 = x
100 * ✓(2)/2 = x
50 ✓2 =x
x = 50✓2 ft
Ln20+ln5=2ln x
ln(20*5) = ln x^2
ln 100 = ln x^2
100 = x^2
x = 10 second option
Y= 1/2x - 1.
the slope is 1/2 and the y-intercept is -1
