Answer:we know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
the height of a triangle is 2*(x-2)

Answer:
The measure of angle A is 32 degrees
Step-by-step explanation:
The picture of the question in the attached figure
In the right triangle of the figure
The tangent of angle A is equal to
----> by TOA (opposite side divided by the adjacent side)
Find the measure of angle A
using a calculator

Answer:
Step-by-step explanation:
Original price = x
75% of 70% of x = $42
0.75*0.70x =$42
x = $42/(0.75*0.70) =$42/0.525 = $80
