Hi there
X+0.32x=82.5
Solve for x to get the cost price
1.32x=82.5
X=82.5/1.32
X=62.5 is the cost price
Hope it helps
X is equal to 30 (vertically opposite angles)
y=180-50
=130 degrees (angles in a straight line equal to 180)
z=180-130-30 (angle sum of a triangle equal to 180)
z=20 degrees
24 is the correct answer:)
And?? More information to answer this..
A is your answer
plug in 8 into x and 2 into y
(8-2)^2 = 8^2 - 2(8)(2)+ 2^2
6^2 = 64 - 32 + 4
36 = 68 - 32
36 = 36 True
hope this helps
