Question

10. Find the value of x. 1 || m. The diagram is not to scale.2 x→260→ mA. 26B.154C. 167D. 13

Answer 1

m has an angle of 180°

Then:

Total angle = 180° = angle 1 - angle 2 = 26° - angle 2

angle 2 = 180° - 26° = 154°

As the same line crosses m and l:

angle 1 = angle x

26° = 2 x

$x\text{ =}\frac{26}{2}\text{ = 13}$
