Answer:
h=24
Step-by-step explanation: In order to solve this we have to apply the Pythagorean Therom which states a^2+b^2=c^2. c^2 being the the hypotenuse. First we have to plug in the values so the new equation is a^2+7^2=25^2. Now we simplify to get a^2+49=625. We can now subtract 49 from both sides to get a^2=576. The final step is to square it to get a=24. So h=24
