Since we know that there are exactly 180 degrees in any triangle, and if each angle is equal to 45 degrees, we must add 45 to 45 and then subtract the result from 180 to find the 3rd angle. Since 45+45=90,we subtract 180-90 and get 90 degrees or a right angle.
Jean and Jonathans' age illustrate arithmetic sum, and the sum of their ages in three years time is x + y + 6
<h3>How to determine the sum of their ages?</h3>
Currently, their ages are:
Jean = x
Jonathan = y
In 3 years, their ages would be:
Jean = x + 3
Jonathan = y + 3
So, the sum of their ages is:
Sum = x + 3 + y + 3
Evaluate
Sum = x + y + 6
Hence, the sum of their ages in three years time is x + y + 6

Answer: 200 square units
Step-by-step explanation:
first you think what 60/3 is and you get 20
then you multiply 20x20 and get 400
then you divide by 2 because to find the area of a triangle you use the formula (lxh)/2
Answer:
The answer is 48!:)
