Add the three angles and set them to 180
4x-13+15+x+18=180
5x+20=180
5x=160
x=32
Then plug in to get A and C
A=4*32-13
A=115
C=32+18
C=50
Answer: 160

Step-by-step explanation: The value of f(x) when x=-1 is 0.5
Therefore
Step-by-step explanation:
Given that y=f(x)=
to find the f(x) when x=-1 :
That is to find f(-1)
Put x=-1 in the given function f(x)=
Therefore
The value of f(x) when x=-1 is 0.5
