Question

5. If ZAOC = (2x - 13 )" and ZBOC = ( 3x - 12 )", find all the four angles.

Answer 1

Step-by-step explanation:

If this is a parallelogram, then here's the answer.

If ZAOC angle= 2x-13', then the opposite angle will be (2x-13)' also.

Same with (3x-12)'

Sol:

2(2x-13)'+2(3x-12)'=360'

4x-26+6x-24=360'

4x+6x=360+26+24

10x= 410'

x=410/10

x=41'

Now;

2x-13= 82-13

       = 69.

3x-12= 123-12

      = 111.

Therefore,

angles= 69.69,111,111.

Hope this helps,

Thank you.
