The first answer. (3 x 3) + (3 x 4)
Answer:
≈3.46
Step-by-step explanation:
1. Based on the information given in the problem you can draw the triangles shown in the figures attached, which are not drawn to scale ("x" represents the lenght of the hyteponuse in the first triangle, which is equal to the lenght of a leg in the second triangle).
2. Calculate x using the first triangle:
![sin(45\°)=\frac{\sqrt{2}}{x}\\x=\frac{\sqrt{2}}{sin(45\°)}\\x=2](https://tex.z-dn.net/?f=sin%2845%5C%C2%B0%29%3D%5Cfrac%7B%5Csqrt%7B2%7D%7D%7Bx%7D%5C%5Cx%3D%5Cfrac%7B%5Csqrt%7B2%7D%7D%7Bsin%2845%5C%C2%B0%29%7D%5C%5Cx%3D2)
3. Now, you can calculate y as following:
![tan(60\°)=\frac{y}{2}\\y=2*tan(60\°)](https://tex.z-dn.net/?f=tan%2860%5C%C2%B0%29%3D%5Cfrac%7By%7D%7B2%7D%5C%5Cy%3D2%2Atan%2860%5C%C2%B0%29)
≈3.46
