Answer:</h3>
= 18°
= 4(18°) = 72°
<h3>
Step-by-step explanation:</h3>
Given:
- One angle in the triangle is 90°
- One angle that isn't 90° is 4 times larger than another angle that isn't 90°
Angles:
= 90°
= x
= 4x
Solution Pathway:
Under the rules for any triangle, a triangle's interior angles must add up to 180°. Using this, we can set up the equation:
- sum of the interior angles = 180°
Now let's solve for x.
- 90 +x + 4x = 180
- 90 + 5x = 180
- 5x = 90
- x = 18°
Now that we know x is 18°, lets plug this value into the two unknown acute angles.
- = 18°
- = 4(18°) = 72°
