Answer:
∠DCF is 100°
Step-by-step explanation:
Given tangent AD and secant FB intersect at point C, the point of tangency. We have to find the measure of ∠DCF.
As, ∠COF=160°
In ΔCOF, by Angle Sum Property of triangle
∠OCF+∠COF+∠OFC=180°
⇒ ∠OCF+160°+∠OCF=180° (∵OC=OF)
⇒ 2∠OCF=20° ⇒ ∠OCF=10°
Now, we have to find the ∠DCF
∠DCF=∠DCO+OCF
As radius from the center of circle to the point of tangency is perpendicular to the tangent line.
∠DCF=∠DCO+OCF
=90°+10°=100°
(7x^4)(3x)^3
(7x^4)(27x^3)
7 x 27 x x^7
189x^7
Answer:
112
Step-by-step explanation:
Looks like the answer would be 219 people since you can't have half a person.
The answer would actually be A
F(x)=3x^2+4x
G(x)=2x^2-x+1
The two x^2 items are both positive and are added together to be 5x^2
The two x items would be added together to get 3x cause of the -x
Then +1 is just +1
Making the equation 5x^2+3x+1
If we were subtracting you would be absolutely correct, but since we are adding would go the opposite direction.
I hope this helps!
