Question

if a right triangle has an angle that is $55^\circ$, what is the third angle in the triangle? (1 point)
$15^\circ$
$25^\circ$
$35^\circ$
$45^\circ$

Explanation:

Step1: Recall right triangle angle sum

The sum of angles in a triangle is $180^\circ$, and a right triangle has one $90^\circ$ angle.

Step2: Subtract known angles

Let the third angle be $x$. Calculate:
$x = 180^\circ - 90^\circ - 55^\circ$

Step3: Compute the result

$x = 35^\circ$

Answer:

35° (Option C: 35°)
