What is A = 8x + 74 degrees and B = 2x + 56 degrees solve for x and then find the measure of B
Novosadov [1.4K]
Since those lines are parallel, we know that A + B = 180°

So, we have:

8x + 74 + 2x + 56 = 180
10x + 130 = 180
10x = 180 - 130
10x = 50
x = 5

B = 2x + 56
B = 10+56=66

(To check:
A = 8x + 74
A = 40+74=114
114+66=180)

I need help for this one do I add them up and equal them to 180?
nikitadnepr [17]
The measure of angle 1 is 210 degrees.

You'll have to draw an auxiliary line in between the two parallel lines.

Then, you'll have to find out the angle measures next to 100 and next to 50. Since a line is 180°, then the angle measures next to 100 and 50 are 80 and 130 respectively.

Then, since you have an auxiliary line, you can use the rule of alternate interior angles of parallel lines being equal.

Then from there just add up 80 and 130 to get you 210.
