Step-by-step explanation:
Answer: e = 20, k = 10, h = 25
Step-by-step explanation:
This is an equilateral triangle. It has 3 sides the same, and thus three angles the same. All the angles of a triangle add up to 180, so we can say that the angles of this equilateral triangle have the same value, 1/3 of 180 aka 60. Thus, we can say:
3e = 60 // we can simplify here
(1) e = 20
e + 4k = 60 // if e = 20, then...
20 + 4k = 60
4k = 40
(2) k = 10
k + 2h = 60 // if k = 10, then...
10 + 2h = 60
2h = 50
(3) h = 25
104 is the answer to your problem
Answer:
square root (50) = 7.071
Step-by-step explanation:
Using Pthagoras' theorem, the diagonal length is .
Therefore, the diagonal length is the square root of 5^2+5^2,
=
=
= 7.071
So if Caelyn collected 21 shells in total and her brother collected 4 times as much all you need to do is multiply 21 by 4 and you get your answer which is 84
