Find the measure of the exterior angle.

MaRussiya [10]

Answer:

$120 \degree$

Step-by-step explanation:

The exterior angle in a triangle is equal to the sum of the interior opposite angles in a triangle

Therefore,

$90 + x = 4x$

Now solve for x

$90 + x = 4x \\ 90 = 4x - x \\ 90 = 3x \\ \frac{90}{3} = \frac{3x}{3} \\ 30 \degree = x$

Now let's solve for the exterior angle

$4x \\ 4 \times 30 \\ 120 \degree$

Hope this helps you.
