The angle of 68 elevation to the top of a building is found to be from the ground at a distance of 50 feet from the base of the building. using this information, which expression below could be used to calculate the height of the building?

123.75 feet.

Step-by-step explanation:

Let AB be the height of Building.

BC be length from the base of building.In Δ ABC,

By using trigonometric ratio,

=tan(68°)

=tan(68°)

=2.475

[tan(68°)=2,475]

AB=2.475×50

AB=    123.75 feet

Thus, the height of the building is 123.75 feet.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

- 70

this is the answer for you hope it
