Answer: 30°

Explanation: so we know line F has to be 180° because it’s a line. it tells us the angle is 140°, so we know the interior angle is 40° because 180°-140°=40°. we also know that a triangle is 180°. so we have the two angles of the triangle: 110° and 40°. to find the third angle we find 110°+40°+?=180°. once we solve, we know the third angle is 30° because 180°-150°=30°.

hope this helped!

if (20,14) is an ordered pair of the inverse of f(x) which of the following is an ordered pair of the function f(x)

<h3>(14, 20) is the ordered pair of the function f(x)</h3>

<em><u>Solution:</u></em>

Given that,

(20, 14) is an ordered pair of the inverse of f(x)

We have to find the ordered pair of the function f(x)

In an inverse funciton, the domain of f(x) becomes the range and range of f(x) becomes the domain

To find the ordered pair of the function f(x), we swap the variables x and y

(y, x) of inverse of f(x) becomes (x, y) of f(x)

Therefore, (14, 20) is the ordered pair of the function f(x)
