Answer:
Option C:
Step-by-step explanation:
Hello!
The sum of all angles in a triangle is 180°.
Add up all the angles and solve for x by setting the equation to 180°.
<h3>Solve for x</h3>
- ∠a + ∠b + ∠c = 180°
- (48 - x)° + (9x - 38)° + 90° = 180°
- 10° + 8x + 90° = 180°
- 8x = 180° - 90° - 10°
- 8x = 80°
- x = 10°
Now that we solved for x, we can plug it back into each equation to solve for each angle.
<h3>Angle A</h3>
<h3>Angle B</h3>
- 9x - 38°
- 9(10°) - 38°
- 90° - 38°
- 52°
<h3>Angle C</h3>
The answer is Option C:
Plug them in... -4=x -5=y
-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)
-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)
Therefore the ordered pair IS NOT the solution.
Hope this helps :)
