Answer:

26

Step-by-step explanation:

Because these are remote exterior angles, you set (5x-2) equal to (2x+76)

After you set them equal you solve for x

5x-2=2x+76

5x=2x+78

3x=78

x=26

the answer is 26! i hope this helps you

FG - it is midline. FG = 5.

A midline in a triangle is a line segment connecting the midpoints of two sides.

A midline is half the length of the side to which it is parallel.

Solve for x, angle A, and Angle B
A x+50 B x+80 c72

Answers

I’m assuming you man degrees? Are these angles of a triangle?

This doesn’t really make sense because the angles in a triangle add up to 180° so your equation would be x+50+x+80+72=180

Combine like terms to get
2x+202=180

Then subtract 202 from both sides
2x=-22

So x would be -11 which doesn’t seem right lol

9514 1404 393

Answer:

  ∠A = 39°

  ∠B = 69°

Step-by-step explanation:

We assume these are angles in a triangle, so their sum is 180°.

  A + B + C = 180

  (x+50) +(x +80) +72 = 180

  2x +202 = 180

  2x = -22

  x = -11

Then the angle measures are ...

  A = -11 +50 = 39

  B = -11 +80 = 69

Angles A and B are 39° and 69°, respectively.

What is the equation of the line that passes through the point(-5, -2) and has a
slope of -6/5

Answers

Answer:

         y = -⁶/₅x - 8

Step-by-step explanation:

The slope-intercept form of equation is:  y = mx + b

where m is slope and b is y-intercept

If line y=ax+b passes through point (x₀,y₀) that means

that the equation y₀=ax₀+b is true

(-5, -2)    ⇒   x=-5,   y=-2

m = -⁶/₅

So:

              -2 = -⁶/₅ (-5) + b

               -2 = 6 + b

               b = -8

Therefore equation in  slope-intercept form:

                                                                     y = -⁶/₅x - 8

convert 510° from degrees to radians

Answers

Answer:

[tex]\frac{17\pi }{6}[/tex]

Step-by-step explanation:

To convert from degrees to radians

radian = degree measure [tex]\frac{\pi }{180}[/tex]

           = 510 × [tex]\frac{\pi }{180}[/tex]

           = [tex]\frac{51\pi }{18}[/tex]

           = [tex]\frac{17\pi }{6}[/tex] radians

510 degrees is equal to (17π / 6) radians, which is determined by using the fact that 180 degrees is equal to π radians.

The given angle is  510°.

To convert 510 degrees to radians, we can use the fact that π radians is equivalent to 180 degrees.

First, we convert 510 degrees to radians by setting up a proportion:

180 degrees = π radians

510 degrees = x radians

Solving for x, we find:

x = (510 degrees) * (π radians / 180 degrees)

Simplifying the expression, we have:

x = (17π / 6) radians

Therefore, 510 degrees is equal to (17π / 6) radians.

Is the relation a function? Why or why not?

Answers

Answer:

Step-by-step explanation:

set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!

Answer:

No

Step-by-step explanation:

What makes a function a function is that it only has one input for every output. So in other words the x can't have two y values. But on a graph you can just do the vertical line test to see if the line intersects the vertical line more than once for any x value, it fails. So if we use the vertical line test we can see that for the x value of 2 is intersected by the line more than once, so this isn't a function.

Use the distributive to evaluate each expression
4(12 + 3)

Answers

Answer: 60

Step-by-step explanation:

You do 4*12 and 4*3, 4*12=48, 4*3=12, Next you do 48+12 and you get 60

Answer: 4(12 + 3) = 48 + 12 = 60

Step-by-step explanation: We will use the distributive property to evaluate the expression, 4(12 + 3)

Simply do this by multiplying the number outside of the parenthesis by each number inside of the parenthesis.

4(12 + 3)

4 x 12 = 48 and 4 x 3 = 12

(48 + 12)

Now, add both numbers inside the parenthesis.

(48 + 12 = 60) or 60.
