Given that the measure of ∠x is 90°, and the measure of ∠y is 64°, find the measure of ∠z.
AURORKA [14]

Answer:

<h2><u>26°</u></h2>

Step-by-step explanation:

Assuming that your figure is a triangle, we should keep in mind that all the interior angles of a triangle add up to 180°, always.

So, we have the values of angles x and y as 90° and 64°.

90 + 64 = 154°  ⇒ Add them up.

Now, subtract 154 from 180 to get ∠z.

180 - 154 = <u>26°</u>
