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
Law of sines can be used to solve this problem:
(note - let x represent the missing side length.)
1. set up proportion.
sin 90°/25 = sin 55<span>°/x
2. solve.
(x) sin 90</span>° = (25) sin 55<span>°
(x) sin 90 </span>°/sin 90° = (25) sin 55° / sin 90<span>°
</span>
x = 20.4788011072
rounded to nearest tenth = 20.5
Answer:
Jaylon has completed 12 problems.
Step-by-step explanation:
(This is how I learned it- I'm not sure if you have been taught this way..)
Step 1. Set up a proportion
Step 2. Do 200x 60 to get 1200
Step 3. Get this equation
Step 4. Get the answer of 12
I hope this helps! :)
Answer:
i cannot tell where the seperate numbers are and where the x is multiplication and what numbers are negative. post it agian but put spaces in beetween.
Step-by-step explanation:
remember:
PEMDAS
P- parenthases
E- exponents
M- multiplication
D- division
A- addition
S- subtraction
note:
M, D are tied so do it left to right
A, S are tied so do them left to right
