A triangle has one side measuring 5 feet and two sides measuring 7 feet. What kind of
triangle is it?
equilateral
isosceles but not equilateral
scalene
Answer:
isoceles but not equilateral
Step-by-step explanation:
it has two sides that are the same length, but not all three sides are the same length
An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal

a rectangle has dimensions of (3y+2)cm as the length and (x+7)cm as the other length and 2x cm as the breadth and (x+y+1)cm as the other breadth find the values of x and y and the dimensions
Answer:
x = 4 cm
y = 3 cm
Dimension is 11 by 8
Step-by-step explanation:
The computation of the values of x and y and their dimension is shown below:
3y + 2 = x + 7
3y - x = 5.......(i)
2x = x + y + 1
x - y = 1...........(ii)
Now solve these both equations
2y = 6
y = 3 cm
And,
x - y = 1
x - 3 = 1
x = 4 cm
Now their dimension is
= x + 7
= 4 + 7 = 11
And,
= x + y + 1
= 4 + 3 + 1
= 8
So, 11 by 8
What is the value of y = 7 - 2x when
X=4?
When x = 4, y =

The coordinates of the vertices of △GHI are G(−7,2), H(−2,2), and I(−2,8). Find the side lengths to the nearest hundredth and the angle measures to the nearest degree.
GH = 5, HI = 6, GI ≈ 8.81
m∠G = 90°, m∠H ≈ 50°, m∠I ≈ 40°
GH = 6, HI = 5, GI ≈ 7.81
m∠H = 90°, m∠G ≈ 40°, m∠I ≈ 50°
GH = 5, HI = 6, GI ≈ 7.81
m∠H = 90°, m∠G ≈ 50°, m∠I ≈ 40°

What is the answer? And why does brainly want me have at least 20 characters for my question?
Solve using the substitution method
x = 8y - 4
x + 8y = 6
i will give brainliest and pls show work
You are told x = 8y -4
Replace x in the second equation with 8y-4:
8y-4 + 8y = 6
Combine like terms:
16y-4 = 6
Add 4 to both sides:
16y = 10
Divide both sides by 16:
Y = 10/16
Simplify:
Y = 5/8
Now replace y with 5/8 do find x:
X = 8(5/8) -4 = 5-4 = 1
X = 1, y = 5/8
(1,5/8)

Answer:y=415 x = 21.5
Step-by-step explanation:
We can see 4x-37 = 49
4x = 86
x = 21.5
4(21.5) -3 = 83
Then we can see what the other side is because they are equal
y/5 = 83
83 x 5 = 415
y=415

You are controlling an unmanned aerial vehicle (UAV) for surveillance. The table shows the height y (in thousands of feet) of the UAV x minutes after you start its descent from cruising altitude.
Answer: y=-1/2x+58, decreases 500, begins, 58k
Step-by-step explanation:
I'm not too sure about my equation for the word problem but I can explain how I got it.
The equation is in y=mx+b format, so we need to find the slope. They gave us the graph for a reason. You would take each side of the table and subtract/add. For example: 58-53=-5 (y), 0+10=10 (x).
Then, just put that in rise over run (-5/10).
Simplify. Which gives you -1/2.
They already gave us the y-intercept, so just put it into the equation. y=-1/2x+58.
Keep in mind I don't know if you need to add the 0's because it's thousands of feet, I would just in case though. Hoped this helped!
The equation can be given as [tex]y= -\frac{1}{2}x +58[/tex], and slope for x and y is m that is [tex]\dfrac{-1}{2}[/tex].
Given to us,
x is time in minutes
y is the height (in thousands of feet) of the UAV
x y
0 58
10 53
20 48
30 43
The equation can be given as y = mx+ c
where,
x is time in minutes,
y is the height,
m is the slope,
c is the constant,
Substituting the values of x and y to get m and c,
Equation 1:
[tex]y = mx+ c\\ 58 = m(0) + c \\ c = 58[/tex]
Substituting the values of c to get m,
Equation2:
[tex]y = mx+ c\\53 = m(10) + 58\\m\times (10) = - 58 + 53\\m\times (10) = -5\\m =- \frac{1}{2}[/tex]
[tex]y= -\frac{1}{2}x +58[/tex]
Therefore, the equation can be given as [tex]y= -\frac{1}{2}x +58[/tex], and slope for x and y is m that is [tex]\dfrac{-1}{2}[/tex].
