Step-by-step explanation:
The angles in a triangle add to 180 degrees.
We are given triangle EFG. There are 3 angles: m∡E = 5x+6, m∡F = 4x-6, and m∡G = 5x-2.
The sum of these three angles must equal 180. Set up an equation and solve for x.
Combine like terms on the left side.
Solve for x. 2 is being subtracted from 14x. The inverse operation of subtraction is addition. Add 2 to both sides.
x is being multiplied by 14. The inverse operation of multiplication is division. Divide both sides by 14.
Find the measure of angle G. Substitute x into the original expression.
The measure of angle G is 63 degrees.
