ehidna [41]
The problem is stated incorrectly.  It should be 7 DAYS and NOT years.

ending amount = beginning amount * (1.8)^days
7 years = 2,555 days
ending amount = 30 * 1.8^7
ending amount = 30 * <span> <span> <span> 61.2220032 </span> </span> </span>
ending amount = <span> <span> <span> 1836.660096 </span> </span> </span> or 1,837 (rounded)

The three inside angles (A,B and C) of a right angled triangle are in the ratio 7:18:11
Anastasy [175]

This is overdetermined.  Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:

Answer: A=35°, C=90°, B=55°

We can do it the way they like.

7+18+11 =36

so to get 180 degrees we need to scale the ratio elements by a factor of 5.

7:18:11=35:90:55

A is the smallest.  We see C is indeed a right angle and B is complementary to A.
