Question

I need help with this question

Answer 1

To solve this question we must first find out what is x.

X + x - 4 = 82 degrees

2x - 4 = 82

2x = 86

X = 86/2 = 43.

Here x would be 43 degrees.

We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.
