An angle measures 149.2° more than the measure of its supplementary angle. What is the measure of each angle?
Oksanka [162]
<h2>Solving for the measurements of Complementary Angles</h2><h3>Answer:</h3>

15.4^{\circ} and 164.6^{\circ}

<h3>Step-by-step explanation:</h3>

Recall that Angles that are supplementary to each other add up to 180^{\circ}.

Let a be the measure of the supplementary angle.

If an angle is 149.2^{\circ} more than its supplementary angle, the measure of that angle is a +149.2. The sum of both angles are expressed a +(a +149.2) but since the have to add to 180 as they are supplementary, a +(a +149.2) = 180.

Solving for a:

a +(a +149.2) = 180 \\ a +a +149.2 = 180 \\ 2a +149.2 = 180 \\ 2a +149.2 -149.2 = 180 -149.2 \\ 2a = 30.8 \\ \frac{2a}{2} = \frac{30.8}{2} \\ a = 15.4

Since the other angle measures a +149.2, we can plug in the value of a to find the measure of the angle.

Evaluating a +149.2:

a +149.2 \\ 15.4 +149.2 \\ 164.6

The measure of the angles are 15.4^{\circ} and 164.6^{\circ}

kozerog [31]

Answer:

MON = 130°

Step-by-step explanation:

LOM + MON = 180°

In other words

4z + 30° + 8z + 90 = 180°

12z + 120 = 180

60 = 12z

z = 5

5 x 8 = 40 + 90 = 130°
