Answer:
Ram: 21, Hari: 12
Step-by-step explanation:
To solve the problem, we can use the following notation. We call:
= Ram's age at present
= Hari's age at present
We know that:
- Ram is 9 years older than Hari --> mathematically, this can be written as
- Three years ago, Ram was two times as old as Hari was --> mathematically, this can be written as
where (r-3) is Ram's age 3 years ago, while (h-3) is Hari's age 3 years ago
Substituting eq.(1) into eq.(2), we find:
So, Hari's age is 12; therefore, Ram's age is
What does the triangle look like? If the base angles or two of the side lines are congruent then it is a isosceles triangle. If all the angles are congruent or all the sides, then it is an equilateral triangle. If non of the angles or sides are congruent then it is a scalene triangle
If your sum of all of them added up is 180, then all you will do is add 61+79 that will give you 140 and then subtract that from 180. Your answer should be 40 degrees. :) hope this helps
