Help please, 90-60-30

Mathematics
1 answer:
quester [9]2 years ago
8 0

Answer:

v = \sqrt{2}/2

u = \sqrt{6}/2

Step-by-step explanation:

\sqrt{2} is across from the 60 degree angle so the side across from 30 degrees is half that

the hypotenuse is the product of the side opposite 30 degrees and \sqrt{3}

so:

\sqrt{3} × \sqrt{2}/2 = \sqrt{6}/2
