Answer:

10 & 11 are 29 and 151. 9 is vertical to 10, so it must also be 29 as defined by the first angle. 12 is supplementary to 13, so it must be the difference of 180 by 65: 115. 4 is part of a right triangle, so it must be 45. 7 is vertical to 4 and 3, so adding those angles together will be 70 degrees. By defining what 7 was we now can figure out what 6 is, angle 1 & 7 add up to 99, subtract that from 180 (b/c they're on a flat line.) You recieve 81. Finally angle 8 is supplementary from 9, stating it must be 151. (Oh yea, 14 & 15 are 115 & 65.) Sorry this took so long.

11th grade geometry:

Answer:

The perimeter is 72 units and the area is 149 square units.

Step-by-step explanation:

$\triangle SBA$ has coordinates $S(15,-8),B(-2,21)$ and $A(0,0)$

Using the distance formula.........

Length of side $SB = \sqrt{(15+2)^2+(-8-21)^2}= \sqrt{17^2+(-29)^2}= \sqrt{1130}$

Length of side $BA= \sqrt{(-2)^2+(21)^2}= \sqrt{445}$

Length of side $AS =\sqrt{(15)^2+(-8)^2}=\sqrt{289}=17$

So, the perimeter of the triangle will be: $(SB+BA+AS)= \sqrt{1130}+ \sqrt{445}+17 =71.71... \approx 72$ units. (Rounded to the nearest unit)

The height of the triangle for the corresponding base $SB$ is 8.89 units.

Formula for the Area of triangle, $A= \frac{1}{2}(base\times height)$

So, the area of the $\triangle SBA$ will be: $\frac{1}{2}(\sqrt{1130}\times 8.89)= 149.42... \approx 149$ square units. (Rounded to the nearest unit)

A chord divides a circle into

Pani-rosa [81]

A chord divides a circle into 2 segments.

A major segment and a minor segment.

If the chord passes through the center of the circle, then it divides the circle into equal segments.

I need help i'm really stuck

Ivenika [448]

Answer:

Step-by-step explanation:

If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:

8 * x / 2 = 32

Now, solve:

$8x/2=32\\4x=32\\x=8$

The moon is about 240,000 miles from earth . What is the distance written as a whole number multiplied by a power of ten

Murrr4er [49]

240,000 is a whole number. Now do the power of ten lol. Use a calculator. Remember don't do it all at once. The powers mean multiplying separate for example: 10×10 equals 100. I hundred times10 equals 1000. That is powered by three because it is multiplying 1030 different times which makes it the power. Simple math these days ha ha
