Tanα=height/shadow
α=arctan(height/shadow)
α=arctan(292/131)°
α≈65.84° (to nearest hundredth of a degree)
Answer:
100 joules/ second
Step-by-step explanation:
5,000/50 seconds = 100 joules/ second
Approximately 1.22 hours.
258/3.54≈72.9. 72.9/60≈1.22.
The centre of this circle is at 12

The fourth proportional is found by applying the formula
The product of extremes = The product of means.
The fourth proportional is equal to bc/a and st/r
Let the fourth proportional be x then this can be written as
a:b::c:x
Applying the formula of product of extremes
ax= bc
or
x= bc/a
The fourth proportional can be obtained by multiplying the variables bc and dividing by a
Similarly
Let the fourth proportional be y then this can be written as
r:s::t:y
Applying the formula of product of extremes
ry= st
or
y= st/r
The fourth proportional can be obtained by multiplying the variables st and dividing by r
