The answer is 12/7 or 1 5/7
4x=3/7
x=3/7 times 4
x=12/7 = 1 5/7
Answer:
Unclear
Step-by-step explanation:
Answer:
Perimeter of rectangle added 2 to length:
perimeter of rectangle= length + width + length + width
P = ( l + 2 ) + w + ( l + 2 ) + w
P = 2 ( l + 2 ) + 2 w
P = 4 + 2 l + 2 w
Perimeter of rectangle added 2 to width:
P = l + w + l + w
p = l + ( w + 2) + l + ( w + 2)
p = 2 l + 2 ( w + 2)
p = 2 l + 2 w + 4
The Law of Sines states that
Therefore,
Multiply both sides by sin(53):
AB = 17.25
The answer is D) 17
Answer:
AC = 78
Step-by-step explanation:
Since all the angles are equal (60°), this is an equiangular triangle (meaning all angles re equal). Equiangular triangles are also equilateral meaning that all sides are equal)
We are given then one side is 11x-32 and another side is 5x+28
These two sides must be equal so we can set them equal to each other and solve for x
11x - 32 = 5x + 28
6x - 32 = 28
6x = 60
x = 10
If x = 10, then we can substitute x into either of the two equations to find the length of all three sides (since all sides have equal length)
11(10)-32 = 110 - 32 = 78
AB = BC = AC = 78
AC = 78
