Answer:

<3 = 110

Step-by-step explanation:

The angles are consecutive interior angles. They add up to 180 degrees when the lines are parallel.

<3 + <8 = 180

<3 + 70 =180

Subtract 70 from each side

<3 +70-70=180-70

<3 = 110

Answer:

110 degrees.

Step-by-step explanation:

Angles 2 and 3 are supplementary, and angles 8 and 7 are supplementary.

Angles 3 and 7 are equal.

If angle 8 is equal to 70 degrees, angle 3 is equal to 110.

Answer:

m<BAC= 110 degrees

Step-by-step explanation:

Since the outside angle m<BCD is 130 degrees the inside angle m<BCA would be 50 degrees. At this point you should know that inside angles of a triangle add up to 180 degrees so add the two angles that you know then subtract from 180 degrees. 50+20= 70 degrees and 180-70= 110 degrees.
