The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.
2x+4x-4=80
6x-4=80
6x=84
84/6=14
Angle c = 4 x 14= 56 - 4 = 52
Hope this helps.
Yes because they all have multiples of 3.
Also 4*3=12 and 3*3=9 so 4/3 is equal to 12/9.
