What is m∠v?

round only your final answer to the nearest tenth.

a. 53.9°
b. 56.1°
c. 61.9°
d. 70.0°

c²=a²+b²-2*a*b*cos C> cos C=[a²+b²-c²]/[2*a*b]

in this problem

a=7.6 in

b=8.6 in

c=7.4 in

C=angle V

 cos C=[7.6²+8.6²-7.4²]/[2*7.6*8.6]> 0.5887

C=arc cos (0.5887)> C=53.93°> C=53.9°

the answer is

angle V is 53.9°

b. hoped i'm right lol

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
