Latisha stands 16 feet from a wall where a scoreboard hangs.

From 5 feet above the floor, the angle of elevation to the top

of the scoreboard is 50°. To the nearest tenth of a foot, how

far above the floor is the top of the scoreboard?

HINT: Find the side of the triangle from the person's height to the scoreboard. Then, add 5 feet (the height of the per

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
