Answer: 180*5=900
Step-by-step explanation:
1) Start from the middle triangle and draw 2 lines connecting the edges to the bottom 2 angles. This should result in the crown splitting into 3 sections.
2) Go to the triangles on each side and connect them to the middle triangle. It should result in the crown having 5 triangles.
3) Multiply the 5 triangles by 180 (the angle sum of a triangle) to get 900.
Crown after all the lines are drawn:

Answer:
Ella grew of an inch more
Step-by-step explanation:
For this problem, you want to subtract Ben's growth from Ella's.
This expression would be -
.
To work these out, they must have the same denominator (which should be the lowest common multiple or LCM).
In this case, the LCM is 12, so you want to multiply each side so the denominator is 12. This means the first fraction should be multiplied by and the second by
.
This makes the expression -
, which equals
.
