PLZZZZ I NEED HELP ASAP

Answer:

a=38.21321°

b=14.61693

Step-by-step explanation:

Use cosine rule (c²=a²+b²-2abcosy), where y is the angle, c is the side opposite the angle and a and b are the other two sides.

c²=a²+b²-2abcosy

5²=7²+3²-2(7)(3)cosa

25=49+9-42cosa

42cosa=33

cosa=0.78571428571

a=38.21321°

c²=a²+b²-2abcosy

b=√(15²+9²-2(15)(9)cos70)

b=14.61693
