Answer:
Answer is 31.2
Explanation:
I think you meant to write ∆ABC, but anyways, let's start.
- Your ∆ is a right angle ∆ because two angles are equal to 90° ( 60+30=90) therefore the third angle will be90° by using angle sum of ∆ property:
- Let the third point of ∆ be C. We can find CB by using sine rule:
- By using this CB's value is 10.4
- Now we can find AC by Pythagoras Theorem.
- Which will result in the following:
- Now we can find the area! Input the formula for the area of triangle:
- The answer will turn out to be 31.2
