Find the measure of the angle indicated.

Answers

Answer:

60 degrees.

Step-by-step explanation:

Do you see those red points on the lines? Those red arrows indicate that the lines are parallel, meaning, when there's a line crossing through two parallel lines, are vertical and adjacent angles are the same.

In this case, 11x-6 is equal to 10x.

11x-6 = 10x

-6 = -1x

divide -x both sides, you get x = 6.

Now you know that 11x - 6 = 60, because 11x - 6 = 10x, and since x = 6, 10x = 60.

---------------------------------------------------------------------------------------------------------

Since 10x is on a straight line, the angle next to it adds up to 180, so...

10x + y = 180.

We know that 10x = 60, so 60 + y = 180.

subtract both sides by 60, you get y = 120.

Now, you solved the whole graph.

Answers

Answer:

(y + 6)(y - 4)

Step-by-step explanation:

Factor the following:

[tex] \longrightarrow [/tex] y² + 2y - 24

The factors of -24 that sum to 2 are 6 and -4.

So,

[tex] \longrightarrow [/tex] y² + (6 - 4)y -24

[tex] \longrightarrow [/tex] y² + 6y - 4y - 24

[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)

[tex] \longrightarrow [/tex] (y + 6)(y - 4)

Answer:

( y-4) ( y+6)

Step-by-step explanation:

= y^2 + ( 6 - 4)y - 24

= y^2 + 6y - 4y - 24

= y( y + 6) - 4(y + 6)

= ( y - 4 ) ( y + 6)

3x + 14 = 143

3x = 129

X = 43

Answer:

x = 43

Step-by-step explanation:

lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14

this means that 143 would have to be congruent to 3x + 14

so we can set the equation to 3x + 14 = 143

subtract 14 from both sides: 3x = 129

divide both sides by 3: x = 43
