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°
Answer:
Isosceles triangle basically has two equal sides and angles opposite to these equal sides are also equal.Therefore
50° = 2x°
50/2 = x
25 = x
There fore value of x is 25.
so,angle B = 2 × 25
hence angle B is 50
That's all i can solve, I'm also kinda stuck.
hope this helped
Answer:

i believe thats correct! :)
Step-by-step explanation:
Answer: x=2
Step-by-step explanation:
What you do is you plug the y equation on top and you substitute it in for the y on the equation below. You have -3x=-2(-5x+8)-10
