From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60°    <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64°         <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8°              <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°

The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Dmitry [639]

Answer:

5

Step-by-step explanation:

Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )
