Answer:
64
Step-by-step explanation:
The information can be written as:
Let Alex's number = x
Winnie's number = y
x = 1.75y
x = y + 48
Substitute 1.75y for x:
1.75y = y +48
0.75 y = 48
3/4 y = 48
y = 64
Winnie's favourite number = 64.

Hello!</h2>
The answer is:
![cos(R)=\frac{1}{2}](https://tex.z-dn.net/?f=cos%28R%29%3D%5Cfrac%7B1%7D%7B2%7D)
<h2>Why?</h2>
Since it's a right triangle and we need to know the adjacent side of the triangle, in order to find cos(R), we can use the Pythagorean Theorem.
Pythagorean Theorem formula:
![c^{2}=a^{2} +b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D)
Where:
![c=hypotenuse=20\\a=FirstTriangleSide=AdjacentSide\\b=SecondTriangleSide=OppositeSide=10\sqrt{3}](https://tex.z-dn.net/?f=c%3Dhypotenuse%3D20%5C%5Ca%3DFirstTriangleSide%3DAdjacentSide%5C%5Cb%3DSecondTriangleSide%3DOppositeSide%3D10%5Csqrt%7B3%7D)
So, the adjacent side will be:
![AdjacentSide=\sqrt{c^{2}-b^{2}}=\sqrt{20^{2}-(10\sqrt{3})^{2}}=\sqrt{400-100*3} \\AdjacentSide=\sqrt{100}=10](https://tex.z-dn.net/?f=AdjacentSide%3D%5Csqrt%7Bc%5E%7B2%7D-b%5E%7B2%7D%7D%3D%5Csqrt%7B20%5E%7B2%7D-%2810%5Csqrt%7B3%7D%29%5E%7B2%7D%7D%3D%5Csqrt%7B400-100%2A3%7D%20%5C%5CAdjacentSide%3D%5Csqrt%7B100%7D%3D10)
Now, that we know the adjacent side, we can calculate cos(R), so:
![cos(R)=\frac{AdjacentSide}{Hypotenuse}=\frac{10}{20}=\frac{1}{2}](https://tex.z-dn.net/?f=cos%28R%29%3D%5Cfrac%7BAdjacentSide%7D%7BHypotenuse%7D%3D%5Cfrac%7B10%7D%7B20%7D%3D%5Cfrac%7B1%7D%7B2%7D)
