Answer:
1. 180
2. x = 31
Step-by-step explanation:
1. the sum of the interior angles of every triangle is always 180
2. using what we know from problem 1, we can create an equation:
x + 10 + 2x - 5 + 2x + 20 = 180
add like terms: 5x + 25 = 180
subtract 25 from both sides: 5x = 155
divide both sides by 5: x = 31

Step-by-step explanation:
<h2>
Hello!</h2>
The answer is:
The first option,
<h2>
Why?</h2>
To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".
We are given the function:
Write "f(x)" is equal to write "y", so:
Now, finding the inverse, we have:
Hence, we have that the answer is the first option,
Have a nice day!
