Answer 2

15
65
90
115

Answer 3

what do you think ?? @amberk123

Answer 4

i will think it will be 90

Answer 5

no

Answer 6

see:-
AF is perpendicular angle Bisector,so angle AFN=90 degrees.

Answer 7

correct ????

Answer 8

correct

Answer 9

good

Answer 10

can you find out angle FAN ???

Answer 11

@amberk123

Answer 12

use ANGLE SUM PROPERTY

Answer 13

i am working on it

Answer 14

okk

Answer 15

i got 180 but i think that is wrong

Answer 16

i will re do it

Answer 17

its wrong!!!

Answer 18

angle AFN+angle ANF+angle FAN=180
angle FAN+90+65=180

Answer 19

so what is the value of angle FAN ???

Answer 20

noo

Answer 21

angle FAN=180-65-90=25 degrees

Answer 22

so the answer is 90

Answer 23

no...angle FAN=25 degrees

Answer 24

i know

Answer 25

angle DAf=angle FAN=25 degrees
because AF is perpendicular bisector and it will bisect the angle DAN.

Answer 26

understood ??

Answer 27

What is the measure of angle ADF

Answer 28

angle ADF+angle DFA+angle FAD=180
angle ADF+90+25=180
angle ADF=180-25-90=65

So,angle ADF=65 degrees

Answer 29

use angle sum property in triangle AFD .

Answer 30

understood ??

Answer 31

yes thank you

Answer 32

good and welcome :)
