Step-by-step explanation:
l = length
w = width
l/w = 5/2
l = 5w/2
l×w = 1000ft²
(5w/2)×w = 1000
5w²/2 = 1000
5w² = 2000
w² = 400
w = 20ft
l = 5w/2 = 5×20/2 = 5×10 = 50ft
the length is 50ft.
the width is 20ft.
Answer: it is c
Step-by-step explanation:
First, note that x+21 and 3x+9 are "complementary angles;" they add up to 90 degrees. Thus, 4x + 30 = 90 degrees, so that 4x = 60 degrees, and x = 15 degrees.
