If n // m, which of the following statements are true? Select all that apply. B
2.
3
200
А
60°
A m2 2 = 60°
m
B. m23 = 100
Cm2 2 + m 24 = 80°
D. m2 2 + m23 = 80°

B and C

Step-by-step explanation:

Since m and n are parallel, we can call the two lines extending from the point B transversals.

because they are vertical angles

from the corresponding angles theorem.

from the corresponding angles theorem.

because angle 2 and 4 sum to 80, and because it is a straight angle.

From this, we can see which ones are true.

A is false because angle 2 is 20 degrees.

B is true because angle 3 is 100 degrees.

C is true because angle 2 + angle 4 = 20 + 60 = 80 degrees.

D is false because angle 2 + angle 3 = 20 + 100 = 120 degrees.

Therefore, only B and C are true.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

dude thats to long figure it
