Step-by-step explanation:
<ABD = arcsin 1/5 = 11.5 degree
so <DBC = 90 - 11.5 = 78.5 degree
BD = Square root (5^2 - 1^2) = 4.9
DC = 4.9 * tan 78.5 = 24 (rounded!)
AC = 1 + 24 =25
Answer:
The answer to your question is a) 588.6 N b) 132.3 N
Step-by-step explanation:
Data
mass = 60 kg
weight = ?
Process
1.- Write the formula of weight
Weight = mass x gravity
gravity = 9.81 m/s²
2.- Substitution
Weight = 60 x 9.81
3.- Result
Weight = 588.6 kg m/s² = 588.6 N
4.- Convert Newtons to Pounds
1 pound ----------- 4.45 N
x ----------- 588.6 N
x = (588.6 x 1) / 4.45
x = 132.3 pounds
Answer:
x = 20
y = 7.2
Step-by-step explanation:
12/x = 9/15
9x = 180
x = 20
12/x= y/12
12/20 = y/12
144 = 20y
y = 7.2
y = 20
