question
a side of the triangle below has been extended to form an exterior angle of 134°. find the value of x.
triangle image with 17° angle, x° angle, and 134° exterior angle
answer
attempt 1 out of 2
x = blank submit answer

Explanation:

Step1: Find adjacent interior angle

The exterior angle and its adjacent interior angle are supplementary, so:
$180^\circ - 134^\circ = 46^\circ$

Step2: Calculate $x$ using triangle sum

The sum of angles in a triangle is $180^\circ$, so:
$x = 180^\circ - 17^\circ - 46^\circ$

Answer:

$117$
