if ||M and M6 = 4X - 15 and m7 = x + 30 then m 6 =
Accepted Solution
A:
Answer:15Step-by-step explanation:∠6 and ∠7 are Alternate Interior Angles.The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.m∠6 = m∠7 → 4x - 15 = x + 30 add 15 to both sides4x = x + 45 subract x from both sides3x = 45 divide both sides by 3x = 15
