the area of a right triangle is 336 square centimeters. The base of the right triangle is 48 centimeters. What is the length of
Alex73 [517]

Answer:

50 cm

Step-by-step explanation:

So the first step is to find the height, and to do that you know that the area of a triangle is height * base / 2 =  area. Plugging in the numbers you have, you get:

height*48/2=336

Then, this becomes

height * 24 = 336

Divide both sides by 24

height = 14

Now you can use the base and the height to find the hypotenuse using the Pythagorean Theorem: a^{2} +b^{2} =c^{2}

48^{2} +14^{2} =c^{2} \\2304 + 196 = c^{2}\\2500 = c^2\\50 = c\\c = 50

Therefore the length of the hypotenuse is 50 cm
