Step-by-step explanation:
Represent:
Given that:
Required
Solve for a, b and c
So, we have:
Subtract 1 from both sides

But the adjacent of a triangle can't have a negative measurement.
So:
Recall that:
Substitute 7 for b in the above expressions
Hence, the dimensions of the triangle are:

Ummmmm
The area is 6cm
x-8 to get the zero for the 8 you have to add it. And for the second part you have to subtract four from itself.
