By the law of cosines, the angle

satisfies

which reduces to

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
Answer:
13. 1/2, 5/8, 3/4
16. 7/12, 3/5, 2/3
Step-by-step explanation:
make them have the same denominator.
13) 1/2 x 4 = <u>4/8</u>, <u>5/8</u>, 3/4 x 2= <u>6/8</u>
16) Grab two fractions let's say 3/5 and 2/3
Multiply 3/5 denominator (5) with 2/3 numerator (2)
It's 10 and place it above the number you multiplied the numerator from so it's above 2/3. Do it again but with 2/3 denominator (3) and 3/5 numerator (3). Multiply 3 and 3 you get 9. Place the 9 above 3/5. We know that 9 is less than 10 so 3/5 is less than 2/3. You can do this with any two fractions.
