Step-by-step explanation:

Given are 5 questions with answers as multiple choices 4.

One of the 4 options would be right.

On analysing the answers we find that

BD is a bisector

GF is 15

y =2

Angle DBE=40

FBA=47

Thus we find whatever you answered are perfectly right.

use formula for the circle a=3.14

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.
