Answer:

Area=11,309.73

Step-by-step explanation:

area of a circle is πr^2 so half of the diameter is the radius so it's 60.

pi x 60^2= 11,309.73

The measurement of the supplement of an angle is 7 times the measure of the complement. find the measure of the complement

mamaluj [8]

x = angle 90 - x = measure of complement of x 180 - x = measure of supplement of x From the information given in the problem, we get this: 180 - x = 7 (90 - x) 180 - x = 630 - 7x -x + 7x = 630 - 180 6x = 450 x = 450/6 x = 75. Now we prove that x = 75° is the correct angle: x = 75° = measure of angle 90° - 75° = 15° = meaure of complement 180° - 75° = 105° = 7 (15°)

Answer:

1120°

Step-by-step explanation:

Use the sum of interior angles formula:

$180(n-2)$

Where n is the number of sides.

In a nonagon, there are 9 sides, substitute 9 for n:

$180(9-2)\\180(7)\\1260$

Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:

$\frac{1260}{9} =140$

Subtract 140 from 1260:

$1260-140=1120$

Solve for x -3x+6=2x-24 -30 -6 6 30

Svetach [21]

-3x + 6 = 2x - 24.

Add 3x to both sides.

6 = 5x - 24.

Add 24 to both sides.

30 = 5x.

Divide it all by 5.

x = 6.

What is the order of operation of 100 + 6² - 9

Kipish [7]

Okay so you would use PEMDAS (parentheses, exponents, multiply, divide, add, and subtract) so there are no parentheses so you do the exponents
${6}^{2} = 36$
then you do the rest so 100+36=136 and then 136-9=127 so the answer is 127
