The roof will be in the shape of an isosceles triangle with a base length of 30 m and two sides that are 17 m. The two 17 m beams will have the same angle of elevation since they have to might in the middle.
So to find the angle of elevation, we can split the roof in half vertically to create a right triangle. The base will now be 15 m, and the hypotenuse will be 17. Now we can use a trigonometry function to solve for the angle. We know the hypotenuse and the side adjacent to the angle, so we can use cosine.




The answer is 28.1 degrees
Answer:
386 passengers arrive at Estados Unidos.
386 pasajeros aterrizará en Estados Unidos.
Step-by-step explanation:
English Translation
A plane from Córdoba bound for Estados Unidos and makes stops in Chile and Bolivia. The plane has a capacity for 507 passengers. He leaves the Córdoba airport with 119 empty seats. In Chile 33 passengers go down and 121 go up. In Bolivia 129 go down and 39 go up. How many arrive in Estados Unidos?
- The plane has capacity for 507 passengers.
- 119 seats are empty when it leaves Córdoba.
Meaning that there were (507 - 119) passengers on board = 388 passengers
- In Chile 33 passengers go down and 121 go up.
Number of passenger become
388 - 33 + 121 = 476 passengers
- In Bolivia 129 go down and 39 go up.
Number of passengers become
476 - 129 + 39 = 386 passengers.
Hope this Helps!!!!
T=650mi(hr/50mi)=13 hr
t-1=12 hr
12=650/(50+v) multiply both sides by 50+v
600+12v=650 subtract 600 from both sides
12v=50 divide both sides by 12
v=25/6 mph
v≈4.17mph
Okay so where's the math question(s)?
210=2*3*5*7
none of them
if you meant 2¹⁰ then the answer is A because 2¹⁰=2*2*2*2*2*2*2*2*2*2=(2⁶)(2⁴)
A
