Answer: d) acute isoceles
Step-by-step explanation:
it has 2 acute angles and it's isoceles because it has 2 sides of equal length
Answer:
Step-by-step explanation:
Here, a = 30, b = 16, C = x
By law of cosines
![{c}^{2} = {a}^{2} + {b}^{2} - 2ab \cos C \\ \\ {x}^{2} = {30}^{2} + {16}^{2} - 2 \times 30 \times 16 \: cos 30 \degree \\ \\ {x}^{2} = 900 + 256 - 960 \times \frac{ \sqrt{3} }{2} \\ \\ {x}^{2} = 1156 - 480 \times \sqrt{3} \\ \\ {x}^{2} = 324.615612 \\ \\ x = \sqrt{324.615612} \\ \\ x = 18.0170922 \\ \\ x \approx \: 18.0](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20%20%3D%20%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20-%202ab%20%5Ccos%20C%20%5C%5C%20%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20%7B30%7D%5E%7B2%7D%20%20%2B%20%20%7B16%7D%5E%7B2%7D%20%20-%202%20%5Ctimes%2030%20%5Ctimes%2016%20%5C%3A%20cos%2030%20%5Cdegree%20%5C%5C%20%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%20900%20%2B%20256%20-%20960%20%5Ctimes%20%20%5Cfrac%7B%20%5Csqrt%7B3%7D%20%7D%7B2%7D%20%5C%5C%20%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%201156%20-%20480%20%5Ctimes%20%20%20%5Csqrt%7B3%7D%20%20%5C%5C%20%20%5C%5C%20%20%7Bx%7D%5E%7B2%7D%20%20%3D%20324.615612%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Csqrt%7B324.615612%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2018.0170922%20%5C%5C%20%20%5C%5C%20x%20%5Capprox%20%5C%3A%2018.0)
