Answer:
B. 120°
Step-by-step explanation:
If two tangents intersect in the exterior of a circle, then the measure of the angle formed is one half the difference of the measures of the intercepted arcs.
m∠A° = 1/2(300 - 60)
m∠A° = 1/2(240)
m∠A° = 120
Answer: x=68/11 and y=-72/11
Steps:
2(x+4y=-20)
2x+8y=-40
2x - 3y = 32
- 2x + 8y = -40
-11y=72
y=-72/11
x + 4(-72/11) = -20
x - 288/11 = -20
x=68/11
Has to be B, because it’s the only one that touches the point 2 on the x axis
