2

x+4=12

Step 2: Subtract 4 from both sides.

The measure of m<JMO is 20 degrees

The triangle JOK is a 60 degrees equilateral triangle. Hence the measure of m<O at the center is 60 degrees.

<h3>Angle at a point</h3>
  • The sum of the angle at a point is 360 degrees.

Since the base angles of triangle KOL and OLM are equal hence;

  • m<KOL + m<MOL + m<JOM + m<JOK = 360 (angle at a point)

Substitute the base angles and the equilateral angles to get angle JOM

80 + 80 + m<JOM + 60 = 360

m<JOM = 360 - 360 - 220

m<JOM = 140 degrees

<h3>Sum of angles in a triangle</h3>

Since the sum of angle in the triangle JOM is 180 degrees, hence;

2m<JMO + m<JOM = 180

2m<JMO = 180 - 140

2m<JMO = 40

m<JMO = 20 degrees

Hence the measure of m<JMO is 20 degrees

Determine the value of x in the diagram.<br> 112<br> x<br> &lt;<br> 68<br> 112<br> =
nasty-shy [4]

Answer:

The value of x is 68, all the angles in a parrelelogram equal 360, 68 + 112 + 112 + x = 360, all the angles are 292, and subtracted from 360 you get 68

What is the measure of x?
Pavlova-9 [17]
We know angle BAD= CBA so we can do:
42+105 + x = 180
x = 180-105-42
x=33

Hope this helps!! :)
