Step-by-step explanation:
Formula : Pi×r²
pi×2²=4pi=12.56637061
rounded : 12.57cm
After sale, the price is $135
75% is $135
so 100%
(135/75) * 100
(135/3) * 4
45 * 4
$ 180

Answer:
<A = 67
Step-by-step explanation:
The three angles of a triangle add up to 180 degrees. We know a right angle is 90 degrees.
<A + <B + <C = 180
3x-8 + 90 + x-2 =180
Combine like terms
4x-10+90 = 180
4x+80 =180
Subtract 80 from each side
4x+80-80=180-80
4x=100
Divide each side by 4
4x/4 = 100/4
x=25
But we want to know <A
<A = 3x-8
Substitute x=25
=3(25) -8
=75-8
= 67
