Is the triangle an equilateral triangle

Mathematics

solong [7]4 years ago

It is not an equilateral triangle. To prove this, you must solve for x. I found x by setting 2x+5.2 = 3x+1.2 to get x=4. Then I plugged 4 into equation to see if they were equal. 2(4)+5.2= 13.2 and 3(4)+1.3=13.2 but 2(4)+6.2=14.2. This allows us to conclude that the triangle is not equilateral because all of the sides are NOT congruent. Hope that helped:))

The round off value of 10256/32548 up<br>to three decimal places<br>Is​
Troyanec [42]

Answer:

0.315

Step-by-step explanation:

10256/32548 is about 0.3151 (I used calculator)

0.3151 rounded to thousandth place is 0.315

Remember the rule when round, 5 and above, up, below 5, stay the same.

The number after 5 in 0.3151 is 1 and 1 is less than 5, so the 5 stays the same.

A line passes through (-1,7) and (2,10) which answer is the equation of the line
alekssr [168]

Answer: -x + y = 8

Step-by-step explanation:

So first you are going to want to find the slope of the equation. The equation for that it (y2 - y1)/(x2 - x1) = (10 - 7)/(2 - -1) and that equals 1. So your slope will be 1.

Now you have half of your equation complete, currently it looks like, y = x + b. So we have to find the y intercept. You can do that by plugging in a pair of coordinates into the current equation and solve for b.

Lets plug in (2,10)

10 = 2 + b

10 - 2 = b

b = 8

So now you have your equation in slope intercept form, y = x + 8. Just move the x over to the left side and there is your answer.

-x + y = 8

Find the missing side of the triangle :)
kati45 [8]

Answer:

x=15

Step-by-step explanation:

Hey There!

So what we want to do is inverse operations from the formula of area of a triangle

The area is equivalent to

A=\frac{hb}{2}

h=height

b=base

now we setup an equation with what we are given

we are given A (area) and h(height)

so the equation looks like...

75=\frac{10b}{2}

now we solve for b (x)

step 1 multiply each side by 2

75x2=150

/2x2 cancels out

now we have

150=10b

step 2 divide each side by 10

150/10=15

10/10 cancels out

b=15

We can conclude that the base (aka x) is equal to 15
