(brainiest)Which letter would be the most meaningful variable for this problem situation? The height of a wall increased by 6
A. m

B. h

C. i

D. y

We can use the variable h because the initial letter of height is h. Thus, It is the most suitable variable to represent unknown height. The equation for this situation will be;

m∠a is 90°

m∠b is 40°

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
