There are several ways to solve this problem. The easiest one is by trigonometry. I am going to apply this method. If you didn't see trigo yet, I will use the triangles semi equilateral.
Let BD, be the wall on the left and CE on the right (B and D = base of the wall)
1) In Δ BAD, angle BAD = 60°→→ tan (60) =(opposite side)'(adjacent) =BD/DA
tan (60) = 60/DA , but tan (60) = √3 →→√3 = 60/DA or DA = 60/√3
And DA = 34.64
2) In Δ ACE, angle CAE = 30°→→ tan (30) =(opposite side)'(adjacent) =EC/AE
tan (30) = 40/AE , but tan (30) = √3/3 →→√3/3 = 40/AE or AE = (40)/(√3/3)
And AE = 68.28
3) Distance between walls = DA + AE = 34.64 + 68.28 = 103.92
(If you didn't study trigo yet, do let me know then we will solve it with the semi equilateral triangles
Y=7
This line is parallel of x - axis .
For all of the values , y values is 7
Good Luck :)
Answer:
4
Step-by-step explanation:
Just plug in y = -6 and solve for x!
4x + y = 10
4x - 6 = 10
4x = 16
x = 4
Answer:
The pail would be 8/15 full.
Step-by-step explanation:
First we convert 1/5 and 1/3 to have the same denominator.
5 and 3 can become 15 when multiplied together.
1/5 = 3/15 and 1/3 = 5/15
Now we add both together.
3/15 + 5/15 = 8/15
So the answer is 8/15.
Hope this helps! :)
