Answer:
A
Step-by-step explanation:
Answer: x = 40
have: ∠A + ∠B + ∠C + ∠D = 180°
⇔ x + 6 + x + 4 + x +10 + x = 180°
⇔ 4x + 20 = 180
⇔ x = (180 - 20)/4
⇔ x = 160/4 = 40
Step-by-step explanation:
Whats the question suposed to say
For L to be parallel to M, then 7x - 7 must be equal to 4x + 14, as they are alternate angles along 'parallel lines'.
Thus, 7x - 7 = 4x + 14
3x = 21
x = 7
