Answer:
150°
Step-by-step explanation:
Consider OACB,
Here <CAO =<CBO= 90° ( As they are tangents)
<ACB= 30°
Now, <CAO +<CBO+<ACB+x= 360°
90°+90°+30°+x= 360°
x= 150°
Hope it helps

The total length is:
Express fraction as improper fraction
Answer:
.4 repeating
Step-by-step explanation: divide the top number by the bottom number so 4 divided by 9
No solution means that the lines are paralell and have differnt y intercepts
paralell means has same slope
y=mx+b
m=slope
b=yint
given equation is
y=-3x+5
slope=-3
yint=5
paralell so
y=-3x+b
wher b is any number except 5
example
y=-3x+4
y=-3x+√3
y=-3x-π
basically
m=-3
b=any number except 5
