y = 6°
Step-by-step explanation:
Hello!
All 3 sides of the triangle are equal, indicating that it is an equilateral triangle. The rules of this particular triangle say that all angles are equal to 60°.
We can solve for x by setting the equation 7x+4 to 60.
<h3>Solve for x</h3>
- 7x + 4° = 60°
- 7x° = 56°
- x = 8°
The value of x is 8°.
We can go ahead and solve for y by setting that equation to 60°.
<h3>Solve for y</h3>
- 8y + 12° = 60°
- 8y = 48°
- y = 6°
The value of y is 6°.
