Answer:
x = 110°
Step-by-step explanation:
The Outside Angle Theorem states that the measure of the angle formed by two secants or a secant and tangent from a point outside of a circle is half the difference between the two arcs.
This means that ½ (210 – x) = 50.
½ ( 210 – x ) × 2 = 50 × 2
210 – x = 100.
210 – x + x = 100 + x.
210 = 100 + x.
100 + x = 210.
100 + x – 100 = 210 – 100.
x = 110.
This value must be true because:
½ ( 210 – 110 ) = 50.
½ ( 100 ) = 50.
50 = 50.
Answer:

Step-by-step explanation:
-6y=8x-4
0=8x+6y-4---(i)
slope (m1)=<u>-coefficient</u><u> </u><u>of</u><u> </u><u>x</u>
coefficient of y
=<u>-8</u>
6
= <u>-4</u>
3
As the lines are parallel,
m1=m2
so,
The slope of line parallel to the line having equation -6y=8x-4 is <u>-4</u>

Answer:
C) Consistent and Dependent.
Step-by-step explanation:
As the system has at least ONE solution. Both lines lie over each other, which makes them dependent.
The system, therefore, is consistent and dependent.
