Answer:
x=23°; θ=87°
Step-by-step explanation:
These two angles create what is known as supplementary angles, or 2 angles that add up to 180°. We know this because all horizontal lines are 180° on either side. Since we know the total value of these two angles should equate to 180°, we can set up a simple equation:
Now, using algebra, we can solve for x:
Plugging x back into the equation, we get:
Therefore, the total angle is equal to 87° and x is equal to 23°.

Answer:
The correct options are: Option A, C and D
Step-by-step explanation:
We need to choose correct options by solving the given system of equations.
Let:
First Multiply equation 2 by 2 and add both equations.
Now, we will put value of x in equation 2 to find value of y
So, we get x = 3.14 and y = 2.14
Solution set is (3.14,2.14)
The given solution set (2,3) is not the solution of system of equations.
If we put x=2 and y =3 in the first equation:
(2,3) when substituted in the First equation the equation is True.
If we put x=2 and y =3 in the second equation:
So, (2,3) when substituted in the second equation the equation is false.
The correct options are: Option A, C and D
