In the figure shown, AD, CE, and FB intersect at point F.

Part A
What is the value of x?

Part B
Describe two different ways you could find the measure of CDF. What is the measure of this angle?

answer: r there any options?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

it has to have an angle of 90 degrees
