Question

$x = \frac{18}{3} = 6$

1. find the measure of $m\angle cab$

$(6x + 10)^\circ$
$(14x - 6)^\circ$

Explanation:

Step1: Set angles equal (angle bisector)

$6x + 10 = 14x - 6$

Step2: Solve for x

$10 + 6 = 14x - 6x$
$16 = 8x$
$x = \frac{16}{8} = 2$

Step3: Calculate each angle part

$6(2) + 10 = 12 + 10 = 22^\circ$

Step4: Sum to find $\angle CAB$

$22^\circ + 22^\circ = 44^\circ$

Answer:

$44^\circ$
