Start by adding together the shortest two sides, 7 and 8.7 inches.  Result:  15.7 inches.  Because this sum is greater than the longest side, 15.4 inches, it's possible to construct a triangle, whose largest angle will be close to 180 degrees.

First off, AY GET OFF OF YOUTUBE BOI XD
Second off, since the area of the triangle is 21 square feet, you do 21/6, which equals 3.5. 
So you need to find (2x-1)= 3.5.
So the answer is 2.25.

Pls help Whats the equation?
SVETLANKA909090 [29]

Answer: y = -5x + 6

Step-by-step explanation:

First, we need to find the slope, which would be m in the equation. To find m, we can use the formula called "rise over run". Here's the formula: m=\frac{y2-y1}{x2-x1}

So, to use this formula, you pick two points from the line that you're given and solve for m.

Let's use the points (1,1) and (0,6). x1 would be 1, x2 would be 0, y1 would be 1, y2 would be 6

m=\frac{y2-y1}{x2-x1}

m=\frac{6-1}{0-1}

m=\frac{5}{-1}

m=-5    So, the slope is -5

Then, we need to find the y intercept, which would be b in the formula.

We can see that the point where the line meets the y axis is at (0.6), so the y intercept would be 6.

Now let's put everything together:

y = mx+b

y = -5x + 6

Help find the missing lengths round to nearest tenth
Mama L [17]

Answer:

<h2>x = 20.8</h2><h2>y = 22.3</h2>

Step-by-step explanation:

  • Theta is 21 degrees
  • x is the adjacent side
  • 8 is the opposite side
  • y is the hypothenuse

SOH - CAH - TOA

Since the opposite side is given and we need to find the length of the adjacent side, we can use tangent to solve for x.

tan 21=\frac{opposite}{adjacent} \\tan 21 =\frac{8}{x} \\0.384 =\frac{8}{x} \\0.384x =8 \\x=\frac{8}{0.384} \\x=20.84

Since the opposite side is given and we need to find the length of the hypotenuse, we can use sine to solve for y.

sin 21=\frac{opposite}{hypotenuse} \\sin21 =\frac{8}{y} \\0.358 =\frac{8}{y} \\0.358y=8 \\y=\frac{8}{0.358} \\y=22.32

Which equation can be used to find the perimeter of the rectangular chalkboard
Alik [6]

If the chalkboard is just rectangular we can just use:

(2 x L) + (2 x W)

or

L+L+W+W

L= Length

W= Width
