Answer:
54.3deg
Step-by-step explanation:
sin(angle) = 65/80
angle = 54.34deg
The end answer is 40.75cm^2 (squared)
How i got there was i used the equation
1/2 (a×b ) + 3/2 (b×s)
where A is the height of the base triangle
Where b is the side length (it does not matter which one but it is one of the 5's)
The second b stands for the same thing.
Where S represents the height of the pyramid.
So then we get this:
1/2 (4.3 × 5) + 3/2 (5 × 4)
you solve the parentheses first and so on and so on.
I hope this helps!! Have a good day and remember to be tiger fierce!! :p

Answer:
<u>The best estimation of the fraction of the batch that was left is 5/84</u>
Step-by-step explanation:
Mr. Gallegos has:
A batch of muffins = 1
He gave 11/21 of the batch to his neighbors:
1 - 11/21 = 21/21 - 11/21 = 10/21
He ate 1/8 of the batch himself:
10/21 - 1/8 = 10/168
= 10/168 (dividing by 2)
= 5/84
<u>The best estimation of the fraction of the batch that was left is 5/84</u>
