<u>Solutions given;</u>
<u>Using cosine rule</u>
b²=a²+c²-2*a*c*cos B°
b²=15²+8²-2*15*8*cos39
b²=102.48
b=
b=10.12
b=10.1
<u>Using sine rule</u>


<u>Doing criss cross multiplication</u>
Sin C=
m<C=Sin -¹(0.29)
m<C=14.98
<u>m<C=15°</u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>
Answer:
oh hey I gotchu-
first of all you are gonna make that into two rectangle by slicing the top off if that makes sense so you now have a large rectangle (11×12) and a small one (3×8) now you use the area formula for rectangles base×height so the small one becomes (3×8)=24 and the large one is (11×12)=132. now to make them into one shape for the total area you add those two values 132+24=156 so your total area is 156m²
