WILL MARK BRAINLIEST AND 15 POINTS

Answer:

40

Step-by-step explanation:

AFE=120 so arc AE is also 120

those 3 angles add up to 180 and 180-120-20=40

The measure of ∠C is 40°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Angle measure of central angle is equals to measure of intercepted arc.

External angle formed outside a circle,

= Half the difference of the major and minor arc =

Angle measure of AFE

= arc AE = 120°

Thus:

m∠C = 1/2(120 - 40)

m∠C = 40°

So, the angle measure of C is 40°

Therefore, 40° is the measure of ∠C.

Answer:

a=300 and k=200

Step-by-step explanation:

Multiply the first equation by -10,and multiply the second equation by 1.

−10(a+k=500)

1(10a+3k=3600)

Becomes:

−10a−10k=−5000

10a+3k=3600

Add these equations to eliminate a:

−7k=−1400

Then solve−7k=−1400for k:

−7k=−1400 (Divide both sides by -7)

[tex]\frac{-7k}{-7} =\frac{-1400}{-7}[/tex]

Now that we've found k let's plug it back in to solve for a.

Write down an original equation:

a+k=500

Substitute200forkina+k=500:

a+200=500

a+200+−200=500+−200(Add -200 to both sides)

a=300

Answer:

L=7.94 feet, W=9.88 feet

Step-by-step explanation:

perimeter=78 feet

LxW=78

2L-6=W

substitute

Lx(2L-6)=78

2L^2-6L=78

2L^2-6L-78=0

factor

(2L-15.86)(L+4.95)=0

2L=15.88, L=7.94

L=-7.94 feet

Answer:

The equation is = I = [tex]e^{4.8}[/tex]

Step-by-step explanation:

As given ,

M - magnitude of an earthquake

I - intensity of earthquake

I₀ - intensity of a reference earthquake

The relation between the three is as follows :

M = log([tex]\frac{I}{I0}[/tex] )

As given -

M = 4.8,  I₀ = 1

⇒ 4.8 = log([tex]\frac{I}{1}[/tex]) = log(I)

⇒ 4.8 = log(I)

⇒I = [tex]e^{4.8}[/tex]

So, the equation becomes I = [tex]e^{4.8}[/tex]

Answer: Perpendicular lines

Step-by-step explanation:

The first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.

The two equations, y - 2 = x + 20 and y - 2 = -(x + 20), represent linear equations in standard form. Let's break down each equation:

y - 2 = x + 20

This equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the value of x plus 20. This equation can be rearranged to slope-intercept form (y = mx + b) by isolating y:

y = x + 20 + 2

y = x + 22

The equation y = x + 22 represents a line with a slope of 1 and a y-intercept of 22.

y - 2 = -(x + 20)

Similarly, this equation represents a linear relationship between x and y. It states that the value of y minus 2 is equal to the negative of the value of x plus 20. This equation can also be rearranged to slope-intercept form by isolating y:

y = -(x + 20) + 2

y = -x - 20 + 2

y = -x - 18

The equation y = -x - 18 represents a line with a slope of -1 and a y-intercept of -18.

In summary, the first equation (y - 2 = x + 20) represents a line with a positive slope and a y-intercept of 22, while the second equation (y - 2 = -(x + 20)) represents a line with a negative slope and a y-intercept of -18.
