Answer:
1. 30ft
2. 0.4 min
Step-by-step explanation:
In this question, apply sine law which states that sine Ф= opposite/hypotenuse
The general formulae; is SOHCAHTOA where ;
(SOH) sineФ=opposite/hypotenuse ; (COH) cosine Ф= adjacent/hypotenuse and (TOA) tan Ф=opposite/adjacent
In the question the height of the two floors is the " c" and the angel at the base is 60° and distance the conveyor travels is the hypotenuse
Hence;
![Sin 60= \frac{26}{H} \\\\\\H=\frac{26}{Sin60} \\\\\\H=30 ft](https://tex.z-dn.net/?f=Sin%2060%3D%20%5Cfrac%7B26%7D%7BH%7D%20%5C%5C%5C%5C%5C%5CH%3D%5Cfrac%7B26%7D%7BSin60%7D%20%5C%5C%5C%5C%5C%5CH%3D30%20ft)
If 75ft=1min
30ft=?........................simple math
30/75 = 0.4 minutes
Answer:
I don't know sorry it even very hard and diffult for a high school kid
She travels 1800 meters because the bus ride is moot point and she walks home twice once for lunch and once to come home for night and once back to work, so three times 600 meters is 1800 meters
It’s 144
You do a^2 + b^2 = c^2
B is 42 and C is 150 since it’s the hypotenuse
You do it all out and get 22,500 - 1764
Then find the square root and end up with 144
