Question

1. find x. 2x = 55, 2x - 12 = 4x + 43, 17x - 8, find x and m∠c, m∠1 = 28, m∠2 = 36, m∠3 = 62, (17x - 8)°, m∠c =, x =, (4x + 43)°, (2x - 12)°, 4 points, 5 points, 4. find the measure of each missing angle

Explanation:

Step1: Identify the property of the triangle

In an equilateral triangle, all angles are equal and each angle measures 60°. So we set up the equation $17x - 8=60$.

Step2: Solve the equation for x

Add 8 to both sides of the equation: $17x=60 + 8$, so $17x=68$. Then divide both sides by 17: $x=\frac{68}{17}$.

Answer:

$x = 4$
