Answer:
The Pythagorean Theorem states that the square of the hypotenuse (diagonal) of any right triangle is equal to the same of the squares of the two legs. For this situation the television screen is cut by a diagonal of 25 inches and the length of the side is 20 inches.

Answer:
12
Step-by-step explanation:
The area of a triangle is given by A=1/2bh, and from the first line give sus b=4+4h. Therefore we get A=(1/2)(4+4h)h=12. Or (2+2h)h=12. We can simplify further by dividing both sides by 2, and we get (h+1)h=6 or multiplying out h^2+h=6 which gives h^2+h-6=0. This we can factor into (h+3)(h-2)=0 or h=2, or -3. We have a positive hight, therefore, h=2 which gives us a base of b=4+4*2=12. So a base of 12inches. and a hight of 2 inches. We can plug this into the original area formula and see we get an answer of 12
