Ive been doing this problem and i cant decide if its 9, 10, 11, 12, or 13. But i think its 10, thanxs a lot.

If there's a hypotenuse, then you need to use the Pythagorean Theorem:
a²+b²=c²
a=leg
b=leg
c=hypotenuse
Plug in the information you have:
a²+60²=61²
a²+3600=3721
Subtract 3600 from both sides:
a²=121
You have to get the square root of both sides to get "a" alone
a=11

Pythagorean theorem:
A^2 + B^2 = C^2 where C is the hypotenuse
Let A = 60, and C = 61:
60^2 + B^2 = 61^2
3600 + B^2 = 3721
B^2 = 121
B = 11
Check:
60^2 + 11^2 = 61^2
3600 + 121 = 3721
3721 = 3721 (check!)

11
the hypotenuse is 61 so using the pythagoreum therem, A^2 + B^2 = C^2, C is 61, C^2 is 3721
B is for the length 60 so B^2 is 3600
C^2 - B^2 is 3721 - 3600 = A^2 = 121
square root of 121 is 11

If the base is 60units and the hypotenuse is 61 units in length,
By the Pythagoras Theorem,
Perpendicular*Perpendicular=(Hypotenuse*Hypotenuse)-(Base*Base)
=61*61-60*60
=3721-3600
=121
Therefore,
Perpendicular=11 units

properly one way is which you would be waiting to apply the pythagorean theorum that's a squared + b squared = c squared and that interprets to 6 squared + b squared = 11 squared and then b = root 80 5 and that i think of via fact its a 30 60 ninety triangle the hypotenuse would would desire to be 12 and then h would equivalent 6 root 3

well don't forget the formula a^2 + b^2 = c^2 in this case its c^2 - a^2 = b^2. 60 x 60 = 3600 = a^2. 61x61 = 3721 = c^2. 3721- 3600 = 121. The square root of 121 is 11 which is the answer ^.^

61 squared - 60 squared + 121
square root of 121 = 11

People, people people -- the Pythagorean theorum is for RIGHT triangles. We do not know if that is the case here. Also -- why are you giving this person the answer? HELPING would be to provide the necessary formula or point the person in the direction of finding the correct formula.

I think there is a problem in this question. Though you have talked of base and hypotenuse, am not sure if you have in mind a right angled tiangle.
