<h3>
Answer:</h3>
a) TI = 7√3 in
b) IR = 7 in
<h3>
Explanation:</h3>
<u>Using cosine rule</u>:




<u>Using sine rule</u>:




You set both expressions equal to each other, then solve for x. Your answer will be x=12
When you’re finishing the power of a power, you multiply (ex. (x^2•y^3)^3 will become (x^2)^3 • (y^3)^3 = x^6 • y^9
