If both of them are vertical angles, they equal each other. 2x+19=5x-5 is how you would set it up. Add 5 to 19 to get 24 and subtract 2x from 5x to get 3x. 3x=24, so x=8. If you plug that in, your angles should be 35 degrees for each.
Answer:
commutative
Step-by-step explanation:
<span>You are given a rectangular picture measuring 8 inches by 7 inches. Also, Alistair wants this to be framed and that the total area is 34 square inches. The width of the frame is x inches. To solve the dimension of the frame with value of x we have:
We have to assume that x here will be equal to all sides of the frame and so, using the area of the rectangle, we can model the equation like this:
A = LW (where A is the area, L is the length and W is the width)
36 = (8 - x)(7 - x)
36 = 56 - 8x - 7x + x</span>²
<span>x</span>² - 15x +20 = 0 → model of our equation and in quadratic form
x² - 15x + 20 = 0
using a calculator, x = 1.48 inches

3.Use the equation you created in part A to find the width of the picture frame</span>
