The easiest way to do this is the following: if the amount increases with 7% each year, it means that you have to multiply the £400 by 1,07. Then you multiply that answer by 1,07 and one time again. The final answer is 490,0172
I = PRT/100 where P = pricipal, R = rate and T = number of years. I = interest.
So answer is (3250 * 1.7 * 3) / 100 = $165.75
The horizontal distance between the base of the ladder and the wall is: 11.8 foot

<u>Ratio of two angles are 6:13.</u>
So, let the one angle be
and another be 
As we know that,
Sum of all interior angles of a quadrilateral = 
So let's sum up the given angles,






Hence, 
So, First angle

Second angle
