Explain the connection between ∠2 and ∠b.

Angle 2 and Angle B are both the same

180-50-65= 65 (angle sum of a triangle is 180 degrees) B = 65 degrees

180-50-65= 65 (angle sum on a straight line is 180 degrees) 2= 65 degrees

Thus Angle 2 and Angle B are both the same

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
