The sum of the measures of the angles in a triangle is always 180 degrees.

If you follow the procedure in the question, you will have a straight angle when you put the pieces together. All straight angles have 180 degrees. Therefore, there are 180 degrees in every triangle.

What is X in the equation -15x+15(-4)=-30
love history [14]

<em><u>Answer: x=-2 *The answer should be the negative sign.*</u></em>

Step-by-step explanation:

distributive property: a(b+c)=ab+ac

remove parenthesis

-15x-15*4=-30

15*4=60

-15x-60=-30

add 60 both sides of an equation.

-15x-60+60=-30+60

simplify.

-15x=30

divide by -15 both sides of an equation.

-15x/-15=30/-15

simplify.

30/15=2

x=-2

Hope this helps!

Thanks!

Have a great day!

Plzzz help asapppppp what is the inverse of f if f(x)=^3 sqrt x-5
jasenka [17]

Hello from MrBillDoesMath!

Answer:

The first choice, y = x^3 + 5


Discussion:

Let

y = (x-5) ^ (1/3)

To find the inverse, sway x and y and then solve for y:

x = ( y - 5 )^(1/3)         =>             cube both sides

x^3 = y - 5                  =>             add 5 to both sides

x^3 + 5 = y


So the inverse is  x^3 + 5, which is the first choice


Thank you,

MrB

Answer:

53°

Step-by-step explanation:

The angle that measures 143 is vertical to the right angle and the ? angle.

Vertical angles have the same measure. <? + <90 = <143

So do 143 - 90 = 53

So the ? angle = 53

Hope this helps ya!!

Given the sequence 12, 9, 6, 3,........ where x = 0, 1, 2......,
Nitella [24]

Answer:

f(x) = -3x + 12

Step-by-step explanation:

The chart could be represented like this:

x             y

0            12

1             9

2            6

3            3

Suppose that f(x) = y

And substitute x values.

y = -3x + 12

"x = 0"

y = -3(0) + 12

y = 0 + 12

y = 12

"x = 3"

y = -3(3) + 12

y = -9 + 12

y = 3

From the results, it corresponds to the function.
