Answer:

61

Step-by-step explanation:

The sum of the three angles of any triangle is equal to 180 degrees.

180-58=122

122/2=61

We divide by two because we are missing the other two angles but they are both equal.

I need answers to this
ololo11 [35]

Answer:

x = -5, and y = -6

Step-by-step explanation:

Suppose that we have two equations:

A = B

and

C = D

combining the equations means that we will do:

First we multiply both whole equations by constants:

k*(A = B) ---> k*A = k*B

j*(C = D) ----> j*C = j*D

And then we "add" them:

k*A + j*C = k*B + j*D

Now we have the equations:

-x  - y = 11

4*x - 5*y = 10

We want to add them in a given form that one of the variables cancels, so we can solve it for the other variable.

Then we can take the first equation:

-x  - y = 11

and multiply both sides by 4.

4*(-x - y = 11)

Then we get:

4*(-x - y) = 4*11

-4*x - 4*y = 44

Now we have the two equations:

-4*x - 4*y = 44

4*x - 5*y = 10

(here we can think that we multiplied the second equation by 1, then we have k = 4, and j = 1)

If we add them, we get:

(-4*x - 4*y) + (4*x - 5*y) = 10 + 44

-4*x - 4*y + 4*x - 5*y = 54

-9*y = 54

So we combined the equations and now ended with an equation that is really easy to solve for y.

y = 54/-9 = -6

Now that we know the value of y, we can simply replace it in one of the two equations to get the value of x.

-x - y = 11

-x - (-6) = 11

-x + 6 = 11

-x = 11 -6 = 5

-x = 5

x = -5

Then:

x = -5, and y = -6

jada can write 3 1/4 pages in 8 minutes. At this rate, how many pages could jada write in 24 minutes?
makkiz [27]

Answer:

9  3/4  pages = x    

Step-by-step explanation:

\frac{pages}{minutes} = \frac{pages}{minutes}        change 3 1/4 to a decimal

\frac{3.25}{8} = \frac{x}{24}

3.25(24) = 8x

78 = 8x

\frac{78}{8} = x

9.75 = x  

9\frac{3}{4} =x

working with the fraction

3 1/4 /8 = x/ 24

3 1/4 (24) = 8x            

 13/4 (24) = 8x

  316/4 = 8x

  78 = 8x

78/8 = x

9 3/4 = x

X=6 because
9-6=3

X=3 because
2•3=6

X=2 because
1.5 or 1 1/2 • 2 = 3

Not sure if this was what you needed or not!
