Answer:
the answer is 24.
Step-by-step explanation:
The Vertical Angles Theorem states that if two angles are vertical angles, then they are congruent .Given <A and <B are vertical angles so they are equal.
<A=<B.
Measure of <A=x and <B=5x-80
Or 5x-80=x
Adding 80 both sides
5x-80+80=x+80
5x=x+80
Subtracting x both sides
5x-x=x-x+80
4x=80
Dividing both sides by 4
x=20
Measure of <A= x= 20 degrees.
f(x) is concave down on an interval I if all of the tangents to the curve on I are above the graph of f(x)
First graph: h(x) is decreasing but in [1, too) , is rising
D(x) is decreasing
Well, you would I need to multiply all the options : 8x10x12x11
Answer is *10,560*
