Question

a side of the triangle below has been extended to form an exterior angle of 146°. find the value of x.
(there is a right triangle with one side extended to form an exterior angle of 146° and an interior angle x° at the extension vertex.)
answer attempt 1 out of 2
x = input box submit answer

Explanation:

Step1: Find adjacent interior angle

The exterior angle and $x^\circ$ are supplementary, so:
$x + 146 = 180$
$x = 180 - 146$

Step2: Calculate the value of $x$

$x = 34$

Answer:

$34$
