N
in a feg
point h is between points e and f. point j is between points
eh = 12, hf= 28, and fg = 50.
what is fj?
hint: draw your triangle and enter values before writing and solving proportion.
ofj = 35
o fj = 12
of) = 28
fj = 50
o

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles FEG and FHJ are similar by AA Similarity Theorem

see the attached figure to better understand the problem

so

we have

substitute

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
