Answer:
D. Substitution
Step-by-step explanation:
I don't know how to explain it other than that they substituted the 50° angle into the original equation.
Answer:
Given
Step-by-step explanation:
Consider triangle ABD and triangle DCA,
AC=BD ( given that they are diameters)
Diameters of the same circle are equal
AD=AD (common side for both triangles)
<BAD= <CDA (angles in semicircles are 90°)
So since the right angle, hypotenuse and side are equal..
ABD is congruent to CDA
(Rhs congruence rule)
Hence proved..
The perimeter (IP) of a rectangle is
P = 2(length + width)
let width = w then length = w + 88
P = 2(w+w+88) = 2(2w+88) = 4w+176
Thus P = 4w+176 = 7272
hence 4w = 7272 - 176 = 7096
so w = 7096/4 = 1774
width = 1774 inches and length = w+88 = 1774+88 = 1862 inches
Answer:
just graph the line: y=4x-12
Step-by-step explanation:
P = 2w + 2l where w is the width, and l is the length. We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation. P = 2w + 2(w+3).
