Answer the question 1st:
1-corresponding angles=180
then,90+90=180
2-not parallel
3-not parallel
4-corresponding angles=180
x+x=180
2x=180
x=180/2
x=90degree
5-suppose x for two angles
then, same as 4 no. x + x=180
6= alternate angles are always equal.
Answer:
6:45
Step-by-step explanation:
-1/3
at x=0 y= 5
at x=3 y= 4
y=ax+b
b= 5
4=3x+5
3x= -1
x= -1/3
