Answer:
<h2>x = 20</h2><h2 />
Step-by-step explanation:
∠VRW and ∠TRS form a pair of vertical angles then they are congruent
therefore
3x = x + 40
⇔
2x = 40
⇔
x = 20
Your answer should be -x+3
To find the output when you know the input, just plug the input into the function.
x+21=4+21=25
The output is 25.
