We have that cos30=
by the definition of cos as the ratio of adjacent leg over the hypotenuse. Hence, 7/w=1/2 by eradicating square roots. Solving for w in this equation we get that w=7*2=14.
We have that the 3 sides obey the Pythagoran theorem, because:
Hence, the triangle is right. We also have that one side is half the hypotenuse hence one of the other angles of the triangle is 30 degrees because sin30=1/2. Finally, the third angle is 60 degrees because sum of angles=180.
Here, we have that sin 45=p/44=
. Multiplying by 44, we have that p=22
