Answer:
<em>x = 32</em>
Step-by-step explanation:
This is an isosceles triangle since two sides have length 10. The angles opposite the congruent sides are congruent. There is an angle measuring 116 deg, and two angles measuring x. The sum of the measures of the angles of a triangle is 180.
x + x + 116 = 180
2x + 116 = 180
2x = 64
x = 32
1.
a)Two different methods for ordering these wrenches are either
converting the measurements into decimal or converting them into
fractions.
b) I chose to convert them into fractions with an LCD of 16. The fractions
are: 8/16, 12/16, 6/16, 10/16, 5/16, 7/16, 11/16
c) The ordered form of the fractions, from least to greatest, is 5/16, 3/8,
7/16, 1/2, 5/8, 11/16, 3/4
2. I don't see how I can put them on a number line.
3. The number line can definitely be used to support the answer from part C (if it is done correctly). That is because if the order on the number line is the same as the order in C, then we know that C is correct. In addition, since the number line includes benchmarks, we can easily see if the answer to C is incorrect.
Well we know that the perimeters are equal so:
Psquare = Prectangle
we know perimeter for square is the 4 sides of same lengths added up or 4*s
the perimeter of a rectangle is the then4 sides with 2 being equal added up so 2*L + 2*W
we know that a square side equAls s and it says that s=8x. So:
Psqu = 4 * (8x) (substitute 8x for s)
we know that the rectangle L =10x + 8 and W =10. So
Prect = 2 *(10x + 8) + 2 * (10)
we know :
Prect = Psqu so:
4 * (8x) =2 *(10x + 8) + 2 * (10)
32x = 20x + 16 + 20
12x = 36
x = 3
So if x equals 3 we can sub x in for square perimeter
Psqu = 4 *(8 * 3)
P = 4 * 24
P = 96
we can check this with rectangle perimeter
P = 2 *(10 * 3 + 8) + 2 *10
P = 2 * 38 + 20
P = 96
