Step-by-step explanation:
The question implies the two angles are equal because of the positioning of the named vertices. m∠A = m∠E so to say.
You can substitute the values and solve the inequality to find x, then solve for m∠A.
m∠A = m∠E; Given (Inferred)
6x - 8 = 4x + 1; Substitution
6x = 4x + 9; Addition Property of Equality
2x = 9; Subtraction Property of Equality
x = 4.5; Division Property of Equality
m∠A = 6x - 8; Given
m∠A = 6(4.5) - 8; Substitution
m∠A = 19; Solve
Hope this helps!!
