Given b = short side of triangle = 9m
By pythagoras' Theorem,

Answer: -50
Step-by-step explanation: (5-10) then multiply the answer by 10
Circumference = r * 2 * pi
Circumference of track 1 is 376.8
Answer:
Varies directly uses the formula: y/x = k
22/3 = 7.33
105/x = 7.33
105/x (7.33/x) = 7.33(x/7.33)
105/7.33 = x
x = 14.32
14a^2bc^4/21abc^6 = 2a/3b^2
