Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)
= 180°-134°
= 46°
x= 46°
Part B:
120°
The capacity of a jug is 3.5 l correct to the nearest 0.1 l. This places the volume of the jug between 3.50 l and 3.59 l
The capacity of a glass is 0.25 l correct to the nearest 0.01 l. This places the volume of a glass between 0.259 and 0.250 l
The maximum number of glasses that can surely be filled is equal to the whole number that lies just below 3.50/0.259.
3.50/0.259 = 13.51
The required value of the greatest number of glasses that can be surely filled is 13.
