Step-by-step explanation:
Answer:
f(18)=334
Step-by-step explanation:
- f(x)=13x+100
- f(18) = 13(18)+100
- f(18)=234+100
- f(18)=334
<span>supplement angles, sum = 180
lets x = angle
</span><span>its supplement = 180 - x
x + 17x = 180
18x = 180
x = 10
180 -10 = 170
answer
angle = 10
its </span><span>supplement = 170</span>
