<h3>Answer:  w = 31</h3>

===================================================

Explanation:

For any triangle, the interior angles always add to 180

(angle1)+(angle2)+(angle3) = 180

(w) + (4w-6) + (w) = 180

(w+4w+w) - 6 = 180

6w - 6 = 180

6w - 6+6 = 180+6 .... adding 6 to both sides

6w = 186

6w/6 = 186/6 ..... divide both sides by 6

w = 31

------------------------------------

Extra info:

This value of w leads to

4w-6 = 4*31-6 = 118

The three angles of the triangle are: 31, 118, 31

Because we have two congruent angles, this means the triangle is isosceles. The sides opposite the congruent angles are the same length.

Find the radius of a circle that has an area of 6.76 cm². Use it for pi.
Inessa05 [86]

Answer:

<h2>radius = 1.47 cm</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

Area = 6.76 cm²

To find the radius substitute the value of the area into the above formula and solve for the radius

That's

6.76 = \pi \:  {r}^{2}

Divide both sides by π

We have

{r}^{2}  =  \frac{6.76}{\pi}  \\ r =  \sqrt{ \frac{6.76}{\pi} }

r = 1.46689291

We have the final answer as

radius = 1.47 cm

Hope this helps you
