hhheelp me please help i have a hard question please be good :( iam sad nowif u not give me the answer

Step-by-step explanation:

expand the fraction

2×2×2×2÷ 3×3×3×3

16÷81

16/81

simplest form

16/81

The law of Cosines states as follows:

where a is the side opposite angle A, b is the side opposite angle B, and c is the side opposite angle C
for problem 1), we can switch it to:


Now you can use the law of sines for a 2nd angle:

and for the 3rd just use the 180-triangle rule:
C = 180 - 40.08 - 87 = 52.92

Now for problem 2)
again, the Law of Cosines, but now we'll switch it to solve for C:

Now for a 2nd angle use the Law of Sines:


finally, use the 180-triangle rule to find B:
B = 180 - 79.36 - 56.33 = 44.31
