Answer:
x=6.3m
Step-by-step explanation:
Let the opposite side be y in 2nd triangle.
tan 27° = y/9
=> tan 27° X 9 = y
∴ y = 4.585m ≈ 4.59m
cos 43° = y/x
=> cos 43° = 4.59/x
=> cos 43° X x= 4.59
=> x = 4.59/cos 43°
∴ x = 6.276m ≈ 6.3m (corrected to 1 dp)
b=20 yards
15^2+x^2=25^2
225+x^2=625
x^2=400
x=20
finite set is this
even number less than 50 is finite set
yeah
