Someone quickly help! thanks!
Goryan [66]

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:

93+(3x+18)=180

Now, using algebra, we can solve for x:

111+3x=180

3x=69

x=23

Plugging x back into the equation, we get:

3(23)+18=87

Therefore, the total angle is equal to 87° and x is equal to 23°.

Hope this helps!
