In the given triangle with AC=20 and C=30, the measures of the other two sides are:
AB=10
BC=10 √3
In a right triangle with a 30-degree angle, we can use the special right triangle ratios to find the lengths of the sides. In this case, we're dealing with a 30-60-90 triangle. The ratio of the sides in a 30-60-90 triangle is
1: √3 :2.
Let's label the sides of the triangle as follows:
The side opposite the 30-degree angle is the shorter leg (let's call it a).
The side opposite the 60-degree angle is the longer leg (let's call it b).
The hypotenuse is opposite the 90-degree angle (let's call it c).
For a 30-60-90 triangle:
a:b:c=1: √3 :2
Given that c=20, we can find a and b using the ratios. Let's set up the proportions:
1: √3 :2=a:b:20
To find a, multiply both sides of the proportion by 1:
a=1×
=10
To find b, multiply both sides of the proportion by √3 :
b= √3 ×
=10 √3
So, in the given triangle with AC=20 and C=30, the measures of the other two sides are:
AB=10
BC=10 √3
