Answer: a.
Step-by-step explanation:
Step-by-step explanation:
Case 1 :


Case 2 :


<span>The x in this problem represents multiplication, or finding the product of the two numbers. In this case, this problem represents six multiplied nine times, or adding the number six nine times. So the number six added to the number six a total of nine times is fifty-four.</span>
17^2 because the equation for it is a^2+b^2=c^2 so the longest side (x) is the c so 10 i put as a and 7 i put as b. it will always be squared for pythagorean theorem so the equation will look like 10^2+7^2=17^2 and if it isn’t squared all you have to do is undo the squaring
See the attached figure to understand the problem
we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft
tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft
AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft
the answer is
The runners are 199.85 feet apart
