a^2 =2.1^2 + 2.9^2
a^2 = 4.41 + 8.41
a^2 = 12.82
a = 3.58 sq. units
use right triangle-find the length of the missing side : b=2.1, c = 2.9
i know it's start with but don't know how to find a
a^2 =2.1^2 + 2.9^2

see that's the thing my teacher told me it was wrong i had the EXACT answer but he sid it was wrong and that i needed to use the " phythagorean theorem" to solve it
I solved it with the Pythagorean Theorem as though a is the hypotenuse.
Which is the hypotenuse?
Which is the hypotenuse?
the hypotenuse is C=2.9 and i'm looking for A
2.9^2 = a^2 + 2.1^2
0.8^2 = a^2
0.64 = a
0.8^2 = a^2
0.64 = a
thankyou so much! :)
You're very welcome.
