Question

Help please!! just solve for y

Answer 1

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°    (we know that it is equal to 60°, since it is an equilateral triangle)
8y = 64°         (we added both sides by 4 to get the y's alone on one side)
y = 8°              (we divide both sides by 8 to find out what just y is)

Answer:

So y is equal to 8°
