Answer:
s = 76 cm
Step-by-step explanation:
Here, we want to find the value of s in the triangle STU
Since we have the other two sides and the angle facing the missing side, we can use cosine rule
Mathematically, that would be;
s^2 = t^2 + u^2 - 2tu Cos S
s^2 = 96^2 + 98^2 -2(98)(96) cos 46
s^2 = 5749.31
s = √(5749.31)
s = 75.82 which is approximately 76 cm
