Answer:
X: input
Y: output
so if we input -1 we look at the graph to see the y value
2
Hope This Helps!!!
Step-by-step explanation:
When the input is -1 ( the x value is -1) what is the the output ( what is the value of y)
Using the graph, we got to x =-1 and go up and find y =2
When the input is -1 the output is 2
2x+27+x+27=180
3x+54=180
3x=180-54
x=126/3
x=42
angle B=x+27
=42+27
=69 degree
es la B square root of 36/6
