Question

what is the value of c?
(there is a geometric figure with points t, s, u, v. st and sv are marked as equal, angles at t and v are right angles. angle at u is split into c + 22° and 3c. then c = \boxed{\circ}

Explanation:

Step1: Set angles equal (angle bisector)

$3c = c + 22$

Step2: Isolate variable c

$3c - c = 22$
$2c = 22$

Step3: Solve for c

$c = \frac{22}{2}$

Answer:

$11$
