the length of a rectangle is 7 yd more than 5 times the width. the perimeter is 150 yd. find the length and the width.

Vaselesa [24]

P = 2(L + W)
P = 150
L = 5W + 7

150 = 2(5W + 7 + W)
150 = 2(6W + 7)
150 = 12W + 14
150 - 14 = 12W
136 = 12W
136/12 = W
11.33 (or 11 1/3) = W <=== width

L = 5W + 7
L = 5(34/3) + 7
L = 170/3 + 7
L = 170/3 + 21/3
L = 191/3 (or 63 2/3) = L <=== length

Can you help me find length bc please!!!!

Remark

You are dealing with a right angle triangle. You can use one of Sin(x) Cos(x) or Tan(x). Since the Hypotenuse is involved and since you are given the adjacent side, Cos(71) is what you will need.

Solution

H = BC

Cos(x) = adjactent / hypotenuse

Cos(71) = 6.3 / H Multiply both sides by H

H * Cos(71) = 6.3 Divide by Cos(71)

H = 6.3 / cos(71) Cos(71) = 0.32557

H = 6.3 / 0.32557 Divide

H = BC = 19.351 Answer

Which pairs of angles in the figure below are vertical angles?

lara [203]

When you have two lines in an x shape, vertical angles are the ones opposite each other.
in the example here, the angles with the purple dots are vertical angles and the angles with the blue dots are the other vertical angles
