Question

find the value of x...

Answer 1

q1


angle aoc=4x
angle cod=5x
angle dob=6x

by adding the three angles ,
AOC+COD+DOB=180

Now we assume the values
4x + 5x + 6x=180
15x=180
×=180÷15
x= 12

aoc=4x = 48
cod= 5x= 60
dob= 6x= 72

you can do the otger sum with a similar method

Answer 2

in the first question we have 4 x 5 x + 6 x we know that these are forming a linear pair because they are on a straight line so we have 4 x + 5 x + 6 X equal to 180 degree which is equal to 15 X equal to 180 degree and hence the value of x is 180 / 15 equal to 32
