The first one can be done by Pythagoras theorem such as

then

then

The second one can also done by Pythagoras theorem, note that this is isosceles triangle so

, again by using Pythagoras theorem

then

then

For the last one can also done by property of 30-60-90 triangle.

Answer:
440
Step-by-step explanation:
55x8. 8x5=40 carry the 4. 8x5=40+4=44 so it is 440
Let the cherry pies be c and the pumpkin pies be p:
Shawna: c + 3p = 55
Amanda: 3c + 3p = 69
We want to find the cost of c + p. To do this, the easiest way is to divide the second equation by 3:
(3c + 3p)/3 = 69/3
c + p = 23
Therefore, 1 cherry pie & 1 pumpkin pie cost $23.
