Step-by-step explanation:
Answer: No solution
Step-by-step explanation:
I got 3.825
your equation would be
(2x-1)(x+7)=72
when you distribute youd get
2x^2 +13x -7 =72
move the 72 over giving you
2x^2 +13x -79=0
i used the quadratic formula and the answer would be 3.825 because a negative answer wouldn’t make sense in this situation
Answer:
58 ft
Step-by-step explanation:
So I attached a diagram that illustrates the triangle that is formed. We know an angle, as well as the hypotenuse. We are looking for the height, or in other words the opposite side of the angle. There is a trigonometric function defined as: . Using this we can plug in known values and solve for the opposite side, which I'll simply represent as x.
Multiply both sides by 80
Calculate sin(46) using a calculator (make sure it's in degree mode)
Simplify
Round this to the nearest foot
