3 dimes= 30 cent
4 pennnies= 4
30+4= 34 cents
Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
![\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a%5Csqrt%5B%5D%7B3%7D%3D6%5Csqrt%5B%5D%7B3%7D%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Therefore, a=6
u is the opposite side to the 90° angle, therefore

on the other hand, v is the opposite side to the 30° angles, so
<h3><u>Solution:-</u></h3>
This problem can be tackled by using distributive property of multiplication .
It states for any three numbers a,b and c

<u>Similarly</u>,
23 × 45
(21+2) ×45
21×45+2×45
945 + 90
1035
It can also be done as-
23 × 45
(25-2) ×45
25×45-2×45
1125-90
1035
24.69 x 12 = 296.28
296.28 x 1.06 = 314.06
With tax and everything, the total bill rounds up to $314.06. Hope this helped!
