Step-by-step explanation:
4a=2a+4
C.L.T
4a-2a=4
2a=4
=2
The longest angle would be across from the one with the longest side. In this case it would be across from DF
Answer:
no of moles = mass / molar mass
1 mole = 6.02 *10^23 molecules
I don't know if that helped
Answer:
plug it into the pythagorean theorem formula
Step-by-step explanation:
since the pythagorean theorem is a^2+b^2=c^2, you have to plug in the lengths of the leg and the hypotenuse to the formula. If you were trying to find a, you would plug in the second leg into b and the hypotenuse into c. so if for example you needed to find a and the second leg was 2 inches while the hypotenuse was 5 inches, the formula would be a^2+2^2=5^2. then solve it like a regular equation, so a^2+4+25, a^2=21, and you would do the square root of that answer. hope that helped.
