Answer

180^\circ$$

You're on a roll — here are the solutions to the remaining problems.

: The image shows a right-angled triangle. The sum of angles in a triangle is $180^\circ$ . One angle is indicated as $90^\circ$ by the square symbol. The other two angles are $a$ and $3a$ .

Step 1: Set up the equation for the sum of the angles in the triangle. $a + 3a + 90^\circ = 180^\circ$

Step 2: Combine the terms with $a$ . $4a + 90^\circ = 180^\circ$

Step 3: Subtract $90^\circ$ from both sides of the
