Triangle ABC has one angle equal to 90 degrees and AB equal to 5 inches, what is the area of ABC?
(1) BC = 4
(2) AC = 12
it is not necessary to have 3-4-5 or 5-12-13 to have a right angle triangle if the given information is not sufficient as above. right angle triangle can have different measurements of sides. however, no matter the sides of the right angle triangle, it must hold a relationship of its sides as h^2 = l^2 + b^2.
the question seems poorly structured because st 1 and 2 each alone are not sufficient to find the area of the triangle. combined 1 and 2 also doesnot make any triangle.
H could have any value in 1 and 2. in 1, it could be 5 or sqrt(41). in 2, it could be 12 or 13.
so OA you have might be C but it doesnot make any sense.
