<h3>
Answer: 0 degrees (choice A)</h3>
Explanation:
By definition, the floor is assumed to be level and that means the floor is at a 0 degree angle. The shelf must also have this same angle relative to the floor so we have the shelf and floor as parallel planes. For more info, check out the converse of the corresponding angles theorem.
Answer:
D is the right answer just do on edj
Step-by-step explanation:
Answer:
x = 6 x = -7
Step-by-step explanation:
Subtract 12 from each side:
x^2 + x - 30 - 12 = 12 - 12
Simplify:
x^2 + x - 42 = 0
Solve with quadratic formula using both +/- after the first -1:
x = 
Simplify:
x = 6
x = -7
Your answer is B) <span>∠4. Complementary angles are angles that add up to 90 degrees.
