Question

question
find the measure of the missing angles.
(figure with angles 49°, 29° and angles d, e, f)
answer
attempt 1 out of 2
d = \\(\square\\)° e = \\(\square\\)° f = \\(\square\\)°

Explanation:

Step1: Find angle d (vertical angle)

Vertical angles are equal, so $d = 49^\circ$

Step2: Find angle e (vertical angle)

Vertical angles are equal, so $e = 29^\circ$

Step3: Find angle f (supplementary sum)

Angles on a straight line sum to $180^\circ$.
$f = 180^\circ - 49^\circ - 29^\circ = 102^\circ$

Answer:

$d = 49^\circ$
$e = 29^\circ$
$f = 102^\circ$
