You have to find the angle of sunlight and the pole , which then cast a shadow
length of the pole is equal to 3.1m
creating a hypotenuse of 4.52m
the angle will be
[email protected] = opposite side / hypotenuse
= 1.46/4.52
= 0.32 that's 18.66 °
now for the building sin18.66° = opposite/hypotenuse
0.32 = 36.75/ hypotenuse
hypotenuse = 114.84 m
thus using Pythagoras theorem
114.84*114.84 = 36.75*36.75 + x^2
which comes around = 108.8 roughly 109 metres long
Answer:
Slope ratio of first triangle: 3:2
6/4x is the slope but its ratio is the same as the other triangle 3:2
Step-by-step explanation:
Answer:
split the four extra pieces into smaller pieces to were it will give each plate the same amount.
Step-by-step explanation:
Answer is 5
Explanation:
To go from (-1,0) to (0,5) we have to go up 5 units and right one unit.
Rate of change means slope, which is change in y over change in x.
If our change in y is positive 5 and our change in x is positive one, we can put the rate of change as 5/1
This simplifies to 5.
Answer:
b = 32
Step-by-step explanation:
If we are talking a² + b² = c² instead of looking for the hypotenuse we look for a leg and it doesnt matter where it is placed.. so for there forth you'll do
24² + b² = 40²
and then from there you square all the numbers so then you get
576 + b² = 1600
then subtract 576 from both sides so you are left with
b² = 1024
and finally square root it
b = 32
