Answer:
56
Step-by-step explanation:
The angles are 40 degrees and 140 degrees.
• In plane geometry, a figure which is created by two rays or two lines or line segments that share a common end point is known as angle.
• The two rays which are share a common point are called as sides of the angle an the common end point is called as the vertex.
• Some types of angles are acute angle, right angle, obtuse angle, straight angle and many more.
Let one angle be x
Other angle = 7/2 x
Since it is a linear pair, it’s sum will be 180 degrees.
So, x + 7/2 x = 180
9/2 x = 180
9 x = 360
X = 40
7/ 2 x = 7/2 × 40 = 140
Therefore, the angles are 40 degrees and 140 degrees.

Because 5 is in this set, you can already exclude B. 2's factors can not be odd, so that excludes D. and 3's factors doesn't include 20, so you can exclude A.
Answer would be C.
M < 1 = 140
m < 2 = 40
m < 2 + 90 + m < 3 = 180..(total of angles in a triangle are 180)
40 + 90 + <3 = 180
130 + <3 = 180
m < 3 = 180 - 130
m < 3 = 50
Isosceles trapezoid
<ONM = <LON = 100
<OLM = <NML = 1/2(360 - 2(100))
= 1/2(360 - 200)
= 1/2(160)
= 80
Answer
<OLM = 80 degress
