These angles are known as corresponding angles and when added up, they must be equal. So, let's set them equal to that, so we can solve for x, and then angle ABC:

$2x+46=3x-2$

$46=x-2$

$x=48$

Find ABC:

$2(48)+46 = 142$

As per to my calculations, ∠ABC = 142°.

Cable has 24 pennies he has hafe as many nickels as pennies he has 5 more dimes than nickels he has 6 fewer quarters than dimes

Andreyy89

Pennies (P) = 24
Nickels = 1/2P
Dimes = 1/2P + 5
Quarters = (1/2P + 5) -6

Therefore...

Nickels = 1/2P = 1/2(24)= 12
Dimes = 12 + 5 = 17
Quarters = 17 - 6 = 11
