In the diagram below, m_MON = 1249, m _ MOP = 2x + 1, and m2 NOP = 2x
miv72 [106K]

Answer:

The answer is below

Step-by-step explanation:

The Angle Addition Postulate states that the measure of an angle formed by two or more angles which are placed side by side is the sum of the measures of the two angles.

Therefore:

∠MON = ∠MOP + ∠NOP (angle addition postulate)

Substituting values gives:

124 = (2x + 1) + (2x + 1)

124 = 2x + 2x + 1 + 1

124 = 4x + 2

subtracting 2 from both sides of the equation:

124 - 2 = 4x + 2 - 2

4x = 122

Dividing through by 4:

4x / 4 = 122 / 4

x = 30.5

Therefore ∠MOP = 2x + 1 = 2(30.5) + 1 = 62°, ∠NOP = 2x + 1 = 2(30.5) + 1 = 62°

∠MOP = 62°, ∠NOP = 62°

Solve the equation for x.<br> 15 = -2x + 3
bekas [8.4K]

Answer:

<h2>x = -6</h2>

Step-by-step explanation:

-2x+3=15\qquad\text{subtract 3 from both sides}\\\\-2x+3-3=15-3\\\\-2x=12\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{2}=\dfrac{12}{-2}\\\\x=-6
