Answer:
Area of triangle is 25.
Step-by-step explanation:
We have been given an isosceles right triangle
Isosceles triangle is the triangle having two sides equal.
Figure is shown in attachment
By Pythagoras theorem

AD is altitude which divides the triangle into two parts
DC=5 implies BC =10 since D equally divides BC
Let AC=a implies AB=a being Isosceles
On substituting the values in the Pythagoras theorem:




WE can find area of right triangle by considering height AB and AD
Area of triangle ABC is:
(1)

And other method of area of triangle is:
(2)
Equating (1) and (2) we get:



Using area of triangle is: 
Now, the area of triangle ABC=

The first answer is 80, and the second answer is still 65.5. Hope this helps!
To subtract 3/4 - 2/3
1. must find the LCD( Least Common Denominator; the smallest multiple of the denominators of two or more fractions)
2. Combine them
Exact form:
1/12
Decimal form:
0.083
So in fraction form your answer should be:
1/12
