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.
2/3 x (3 - 7/16) = (2/3) * (3+7/16)
= (2/3)*(55/16)
= 55/24
= 2.2917
0.6 x 3.43
= 2.058
The first answer is greater than the second.
Answer: 2/3 x 3-7/16 is larger.
