Answer:
Step-by-step explanation:
area of the rectangle = l×b = 40m
let the breadth be 10m
l = ?
l × 10 = 40
l = 40/10
l = 4m
so the length of the 4 sides = 10m, 10m, 4m, and 4m
since opposite sides of a rectangle are equal

Answer:61.3
Step-by-step explanation:
Using the Law of Sines, you get this formula
sin(angleA)=(a*sin(angleB))/b
sin(angleA)=(14*sin(70)/15)
sin(angleA)=(.88)
angleA=sin-1(.88)
angleA=61.3
