Answer:

x = -6

Step-by-step explanation:

The triangle in the picture is an isoceles triangle in which the measure of top vertex angle is given and one of the base angles is also given.

According to angle sum property of triangle , sum of measure of all the angles of traingle is 180°. Also, in isosceles triangle , the base angles are always equal to each other .

So,

$34 + (x + 79) + (x + 79) = 180$

$= > 2x + 158 + 34 = 180$

$= > 2x +192 = 180$

$= > 2x = 18 0 - 192 = - 12$

$= > x = \frac{12}{ - 2} = - 6$

What is the exact area of a circle with a diameter of 18 feet?

Kitty [74]

The formula for the area of a circle is

$\pi r^{2}$

We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.

$\pi 9^{2} =81 \pi$

So the answer is B, 81 pi square feet

Lana71 [14]

Answer:

4. $648

5. $86.40

Step-by-step explanation:

You take the percent (we'll take 4 for example, so 8%) and change it to a decimal: .08. You then multiply the decimal (.08) by your other number (in this case $600) and the resulting number is your answer, but not final. Take whatever the answer was (in this case 48) and add it to the orignal number (600) to get $648.
