A^2 + B^2 = C^2.
so 49 + 576 = C^2
625 = C^2
Now find the square root of 625.
25 = C (in your case r)
1/2 or 50% is your probibility, whihever you prefrer, fraction or percentage.
Take both sides and multiply them by each other & it will give you X
Answer:
The correct answer is b) 20.78
Step-by-step explanation:
To find this, use the Pythagorean Theorem. Use 12 as the first leg, x as the second and 24 as the hypotenuse.
a^2 + b^2 = c^2
12^2 + b^2 = 24^2
144 + b^2 = 576
b^2 = 432
b = 20.78
