Answer: 90 people
Step-by-step explanation:
3 ladles per person = 150 people x 3
= 450 ladles full
450 ladles full = 5 ladles per one person = 450/5 = 90 people

Answer:
   (b)  112.2 ft
Step-by-step explanation:
The relevant trig relation is ...
   Tan = Opposite/Adjacent
For the given geometry, this becomes ...
   tan(65°) = (height above eye level)/(50 ft)
Then we have ...
   (height above eye level) = (50 ft)tan(65°) = 107.2 ft
Adding the height of eye level will give us the height of the building.
   building height = (eye level height) + (height above eye level)
   building height = (5 ft) + (107.2 ft)
   building height = 112.2 ft

Answer:
20°
Step-by-step explanation:
40°, 70° and 90° are the measures of the three angles of the quadrilateral.
Measure of fourth angle of the Quadrilateral 
= 360° - (40° + 70° + 90°) 
= 360° - 200°
= 160°
Measure of angle 1 will be equal to the measure of the linear pair angle of 160° as they are corresponding angles. 
Thus,


Alternate method:
![m\angle 1 = 180\degree- [360\degree-(40\degree+70\degree+90\degree)]](https://tex.z-dn.net/?f=m%5Cangle%201%20%3D%20180%5Cdegree-%20%5B360%5Cdegree-%2840%5Cdegree%2B70%5Cdegree%2B90%5Cdegree%29%5D)
![\implies m\angle 1 = 180\degree- [360\degree-200\degree]](https://tex.z-dn.net/?f=%5Cimplies%20m%5Cangle%201%20%3D%20180%5Cdegree-%20%5B360%5Cdegree-200%5Cdegree%5D)
