Answer:
22
Step-by-step explanation:
The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
Cef is equilateral so
l=m=n
l+m+n=180
so l=m=n=60
as l=i <span>When two lines intersect, the opposite (X) angles are equal:
</span>or i+j+k=180
i+j=135 eq1
j+k+l=180
j+l=135 eq 2
eq1-eq2
gives i=l
so i=60
g=40
g+h+i=180
h=80
