anonymous · Answer

I'm not sure... I may get the question wrong. You should probably use this formula A=1/2 BH

anonymous · Answer

This is my first time doing this I need like a step by step on how to do it

anonymous · Answer

Hmm, I'm sorry.. I dont get it either lol really wish I did.. but it's confusing

calculusxy · Answer

Use the Pythagorean Theorem 
$$a^2 + b^2 = c^2 $$

welshfella · Answer

use pythagorss theorem

calculusxy · Answer

For question 1 we know that a = 16 and b = 63
so let's plug that into the formula to find c (hypotenuse) 
$$16^2 + 63^2 = c^2 $$

anonymous · Answer

16^2 + 63^ =c^2
lol

calculusxy · Answer

Do you understand how to find the answer to this problem?

anonymous · Answer

4,225?

calculusxy · Answer

Good and then find the aquaria root of 4,225 because when c is being squared, it equals to 4225.

calculusxy · Answer

*square root

anonymous · Answer

65

calculusxy · Answer

correct!

anonymous · Answer

Thank you can you wait until I do the second problem so i can see if its right?

calculusxy · Answer

Sure !

anonymous · Answer

would the answer be 3.5805.?

calculusxy · Answer

Let's check! 

$$a^2 + 2.1^2 = 2.9^2$$
$$a^2 = 4$$ (because 2.9^2 - 2.1^2)
$$a = \sqrt4$$

anonymous · Answer

ohhh okay! I just plugged it in wrong

anonymous · Answer

Thank you! I'll contact you if i need help with anything else

calculusxy · Answer

Sure! and You're welcome :)
