Answer:
Angles in a triangle add up to 180.
ABG - x + 90 + ANGLE AGB = 180
Angles on a straight add up to 180.
CDE - 8x + ANGLE D + 3x = 180
Alterate angles - ATTACHMENT
ANGLE D = x
8x + x + 3x = 180
12x = 180
x = 180/12
<h2>x = 15</h2>
Answer:

Step-by-step explanation:
By definition composite function would be:

Then, if g(2)=3 and f(3)=16, therefore for f(g(x)):
Answer:
15
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Using the given information,
45 = 1/2 * L * 6
45 = 3L simplify
15 = L divide both sides by 3
Answer:
2
Step-by-step explanation:
The coefficient is the number attached to the variable, which in this case is 2.
