Answer:
3/2 =x
Step-by-step explanation:
These two angles are interior angles. They add up to 180 degrees
20x+5 = 24x-1
Subtract 20x from each side
20x-20x+5 = 24x-20x-1
5 = 4x-1
Add 1 to each side
5+1 =4x-1+1
6 =4x
Divide by 4
6/4 = 4x/4
3/2 =x
The measure of the two angles are: [tex]\mathbf{85^{\circ} $ and $ 95^{\circ}}[/tex]
- The figure shows two interior angles that lie on the same side of the transversal.
- Both angles are same-side-interior angles.
- Same-side-interior angles are supplementary angles which add up to 180 degrees
- Therefore:
[tex]20x + 5 + 24x - 1= 180[/tex]
- Add like terms
[tex]44x + 4 = 180[/tex]
- Subtract 4 from both sides
[tex]44x = 180 - 4\\\\44x = 176[/tex]
- Divide both sides by 44
[tex]x = 4[/tex]
- Find the measure of each angle given in the figure
[tex]20x + 5[/tex]
- Plug in the value of x
[tex]20(4) + 5 \\\\= 80 + 5\\\\= 85^{\circ}[/tex]
- [tex]24x - 1[/tex]
- Plug in the value of x
[tex]24(4) - 1 \\\\= 96 - 1\\\\= 95^{\circ}[/tex]
The measure of both angles are [tex]\mathbf{85^{\circ} $ and $ 95^{\circ}}[/tex]
