Subtract (x+109) from 180; the result is 71-x.  The reason for doing this is that we want to equate "corresponding angles."  71-x and x+89 are corresponding angles.  Set them = to one another and then solve the resulting equation for x:

71-x = x+89
-18 = 2x, so x = -9

Now let's determine the angle x+89.  Since x=-9, that angle is 80 (degrees).

So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.

x+109+x+89=180

add the numbers and x's together

2x+198=180

subtract 198 from each side

2x = -18

divide each side by 2

x = -9

Put -9 in for x in the equation x+89 to find that angle

-9+89

=80

ANSWER:

That angle equals 80°

Find the indicated limit, if it exists. (1 point) limit of f of x as x approaches 9 where f of x equals x plus 9 when x is less
Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

For the limit of a function to exist, then the right hand limit of the function must be equal to its left hand limit as shown;

If the function is f(x), for f(x) to exist then;

\lim_{n \to a^{+} } f(x) =  \lim_{n \to a^{-} } f(x) =  \lim_{n \to a } f(x)

Given the function;

f(x) = \left \{ {{x+9\ x

Lets check if the above statement is true.

The right hand limit of the function occurs at x> 9

f(x) = 9-x

\lim_{x \to 9+} (9-x)\\= 9-9\\= 0

The left hand limit occurs at x<9

f(x) = x+9

\lim_{x \to 9^{-} } (x+9)\\= 9+9\\= 18

From the above calculation, it can be seen that \lim_{x \to 9^{+} } f(x) \neq   \lim_{x \to 9^{-} } f(x), this shows that the function given does not exist at the given point.

No. The area of a square/rectangle is length * height, and 4 * 20 is 80m^2. Because Yoshi has a can of paint that can cover 81m^2, and 81m^2 > 80m^2, Yoshi does NOT need to buy more paint.
