If two angles are supplementary, their measures add to 180 degrees.
Let’s name the angles A and B.
You can substitute or replace angle B in the first equation with the second equation like so:
4
So, angle A is 42.5 degrees and angle B is 137.5 degrees!
Answer:
Choice D
Step-by-step explanation:
Several techniques do exist for solving systems of linear equations; substitution method, graphical method and elimination method. For this scenario, since we are not restricted on the method, I opted to use the graphical technique.
The graphical solution to a system of linear equations is the point where the lines intersect. If the lines are never intersect then the system has no solution.
The attachment below shows that the system intersects at the point (-3, 26). Therefore, the system has a single solution: x = -3, y = 26.
Answer:
A - 8/17
Step-by-step explanation:
Substitue the value of theta in the equation in question
Answer: 1) 5280 ft
2) 9.44882 inches
3) 512 ounces
Step-by-step explanation:
Answer:
y = 2x - 3
Step-by-step explanation:
So since we have to put it in y = mx + b form
Subtract 2x from both sides
-y = -2x + 3
Divide both sided by -1
y = 2x - 3
