A moving van ramp has an angle of elevation 28. If the top of the ramp is 5 feet above ground, estimate the length of the ramp. Round to the nearest tenth. Show work.

answer:     true

step-by-step explanation:

just sum

10 + 10 = 20

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
