Find the measures of the supplementary angles of their measures are in ratio of 22:23

Mathematics
1 answer:
Sergeeva-Olga [200]3 years ago
8 0

Answer:

  Measures of the supplementary angles = 88° and 92°

Explanation:

 Two angles that add to 180 degrees is called as supplementary angles.

  Angles are in the ration 22:23

  So, we have

               22a + 23a = 180

               45 a = 180

                    a = 4

      Angles are 22 x 4 = 88 ° and 23 x 4 = 92°

  Measures of the supplementary angles = 88° and 92°

F(x) = -x² + 7x - 12<br> One factor of this is (x - 4). Find the other factor.
saveliy_v [14]

Answer:

(3-x) is the other factor.

Step-by-step explanation:

The given function is :

F(x)=-x^{2}+7x-12

One of the factor is (x-4)

We need to find the other factor.

It can be solved as follows :

F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)

So, the other factor is (3-x).

If the measure of 1 is x and the measure of &lt;2 is x+50, what is the measure of &lt;4?
marin [14]

Answer:

Measure of angle 4 is 115°

Step-by-step explanation:

First, we want to find the measure of angle 2, because the measure of angle 2 is equal to angle 4. When 2 straight lines cross each other, the angles formed are always equal to the angle right across from it.

Find angle 2 by setting up an equation:

x+x+50=180

This is basically saying that angle 1 plus angle 2 equals 180°. In a half turnaround, the angle is 180°. Angle 1 and 2 make up a half turnaround.

Solve the equation:

x+x+50=180

Combine the 2 x's to get 2x.

2x+50=180

Subtract 50 from both sides.

2x=130

Divide both sides by 2.

x=65

Since x=65, plug 65 into x in the measure of angle 2 (x+50).

65+50=115.

Since Angle 2 is equal to angle 4, angle 4 is also 115.
