What do you need explained? I'd be glad to help :)
She totally missed seeing the number 30, as 15 x 2 is 30 and 6 x 5 is 30. 30 is her LCM
well, -12+7 is 5 times (23-7=16) so that answer is 80 and 6-(-5*4=-20) so that is also 16
Hi!
These two angles are alternate interior angles, so they are congruent. Thus:
∠A = ∠B
6x + 5 = 4x + 45
Solve for x:
2x + 5 = 45
2x = 40
x = 20
Solve for ∠A by substituting in this value:
∠A = 6(20) + 5 = 125°
