Answer: 2\sqrt{2}

Step-by-step explanation:

The inradius is given by the area of the triangle divided by the semiperimeter.

The semiperimeter is \frac{12+12+8}{2}=16.

Thus, by Heron's formula, the area is \sqrt{16(16-12)(16-12)(16-8)}=32\sqrt{2}.

Therefore, the radius is \frac{32\sqrt{2}}{16}=2\sqrt{2}}

56 is 80 percent of what number
monitta
Let us assume the number to be = x
Then
(80/100) * x = 56
4x/5 = 56
4x = 56 * 5
4x = 280
x = 280/4
  = 70
The value of the unknown number is 70. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems in future without requiring any help from outside. Only thing that needs to be taken care of is the calculation part.

Where will these 2 lines intersect?<br><br> y = 2x + 7 and x = y + 4
defon
To find the intersecting point, you have to put the two formulas equal to each other
First isolate the same variable, in this case y
So y=x-4

Now we can say
2x + 7 = x - 4

Now solve for x

X= 3

Now fill this in in either one of the formulas

Y= 2 (3) + 7
Y= 13

So they’ll intersect at (3,13)
