To find the measure of the middle sized angle, we first need to find the total number of parts in the ratio. The total number of parts in the ratio is 3 + 10 + 7 = 20.
Next, we need to find the measure of the middle sized angle. Since the middle sized angle is represented by 10 parts in the ratio, we can calculate its measure by finding:
Middle sized angle = (10 parts / 20 total parts) * 180 degrees
Middle sized angle = (1/2) * 180 degrees
Middle sized angle = 90 degrees
Therefore, the measure of the middle sized angle in the triangle is 90 degrees.
The ratio of the angles in a triangle is 3:10:7. What is the measure of the middle sized angle?
