Answer:
B
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees.
We have two angles already and they add up to 60+63=123 degrees
180-123=57
so the remaining angle is 57 degrees
Step-by-step explanation:
∠1 = ∠4 = 57° (vertical angles)
∠6 = 123° (same side interior angles are supplementary)
Given the quadratic equation, (x + 2)^2 = a.
And, x = 1
Solving for the value of a
(x + 2)^2 = a.
a = (x + 2)^2
a = (1 + 2)^2
a = 3^2
a = 9
The value of a is 9
The answer COULD possibly be letter B
Hello!
Here we have $21.28 total spent and paid for with $30. So 30-21.28= $8.72 so our change must equal this amount. The only choice then would be A.
Hope this helps. Any questions please ask. Thank you kindly.
