Answer:
X = 45°
Y = 72°
Step-by-step explanation:
There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.
Answer:
<h2>x = -2 or x = 4</h2>
Step-by-step explanation:
The zeros:
(x + 2)(x - 4) = 0 ⇔ x + 2 = 0 or x - 4 = 0
x + 2 = 0 <em>subtract 2 from both sides</em>
x = -2
x - 4 = 0 <em>add 4 to both sides</em>
x = 4

Answer:
It is the first choice.
Step-by-step explanation:
This is a sequence where
the next term is obtained by adding 6.
first term = -9 + 6(0) = -9
second term = -9 + 6(1) = -3
third term = -9 + 6(2) = 3
4th term = -9 + 6(3) = 9
and 81 = -9 + (6*15).
So the answer is Sigma (-9 + 6n) from n= 0 to n = 15.
