Help me please find x for this triangle!!!!

Mathematics
1 answer:
Ne4ueva [31]3 years ago
5 0

Answer:

x=30

Step-by-step explanation:

Since the measure of an exterior angle is equal to the sum of any two angles in a triangle, the equation would be 4x-18=2x+6+36. Solve this, and we get x=30.

Hope this helped!

Which number line represents the solutions to \x – 5) = 1?
Aneli [31]

Answer:

Second number line represents the [X-5]=1.

Step-by-step explanation:

Given : [X-5]=1 .

To find : Which number line represents the solutions to [X-5]=1.

Solution : We have given that [X-5]=1.

We can se the value x-5 is inside the modulus it may be positive or negative.

So, we will do it by both cases.

1) (x - 5) = 1

On adding by 5 both sides.

x = 1+5 = 6

x = 6.

2) if -(x-5) = 1

remove parenthesis

-x +5 = 1

On subtracting by 5 both side

-x = -4

On dividing by -1 both side

x = 4.

So , x = 4, 6.

Therefore , the second number line represents the [X-5]=1.

Y=3x+4 , 9x-3y=-6 do the lines intersect or are they parallel or are they perpendicular
Angelina_Jolie [31]

Answer:

Lines are parallel.

Step-by-step explanation:

The given lines are y=3x+4,\ 9x-3y=6

Rearrange the equation in the slope intercept form that is y=mx+b where m is the slope.

<em>First Line:</em>

y=3x+4

compare it with y=mx+b

slope (m_{1}) of first line =3

<em>Second Line:</em>

9x-3y=6\\9x-6=3y\\3y=9x-6

divide both by 3

y=3x-3

compare it with y=mx+b

slope (m_{2}) of second line =3

Since slope of two lines are equal

m_{1}=m_{2}=3

hence these lines are parallel.
