A triangular playground has
angles with measures in the ratio
8:3:9. What is the measure of
the smallest angle?
(1 point)
27°
3°
10°
30°
The sum of the angles in a triangle is always 180 degrees.
Let the angles be 8x, 3x, and 9x.
So, 8x + 3x + 9x = 180
20x = 180
x = 9
Therefore, the smallest angle is 3x = 3 * 9 = 27 degrees.
So the answer is 27°.
