We can have:
(10x - 2) - (5x + 2)
Or:
(7x + 3) - (2x + 7)
Answer:
i believe 90 is the answer because if 7+3 is 10, then 9x10 is 90.
Answer:
x = 250°
Step-by-step explanation:
"Angle formed between a chord and tangent intersecting on a circle measure the half of the intercepted arc"
From the figure attached,
Angle between the chord and the tangent = 55°
Measure of intercepted arc (minor arc AB) = h°
Therefore, 55° = 

And m(minor arc AB) + m(major arc AB) = 360°
h° + x° = 360°
110° + x° = 360°
x° = 360° - 110°°
x = 250°
Therefore, measure of the intercepted arc is 250°.
2/cos x
