Question

I WILL MAKE YOU BRAINLYYYYY!!
In the figure, j∥k and m∠1 = 63°.

What is the m∠4?

Answer 1

Answer:

m∠4 = 117

Step-by-step explanation:

m∠1 + m∠4 MUST EQUAL 180

So 180 - 63 = 117

Answer 2

Answer:  117 degrees

=========================================================

Explanation:

Notice how angles 1 and 4 combine to form a straight line, or straight angle. This angle that forms is 180 degrees.

So,

(angle1)+(angle4) = 180

(63) + (angle4) = 180

angle4 = 180-63

angle4 = 117 degrees

Note: The fact that lines j and k are parallel does not effect the answer. We could make j and k nonparallel lines to get the same result.
