Question

13. In the figure, AOB and COD are straight lines. C.
(i) Find the value of x and of y.
(ii) Find obtuse AÔD and reflex CÔE​

Answer 1

Answer:

6x+3y=180---eq1

34+186-4x+3y=180---eq2

subtract eq 1 &2

6x+3y-34-186+4y-3y=0

10x=220

x=22

substitute X in equation 1

3y=180-132

3y=48

y=16

AOD=180-3Y

AOD=180-3Y

=180-48

=132

COE=180-(186-4x)

COE=4x-6

COE=88-6

=82
