And I Think Its B
1. AB is a tangent line to the circle C at point B
∴ AB⊥BC
∴ Δ ABC is a right triangle , ∠B = 90°
∴ AC² = AB² + BC²
BC = radius = 4,000
AC = 4,000 + 22,000 = 26,000
∴ AC² = AB² + BC² = 4,000² + 26,000² = 692 * 10^6
∴ AC = √( 692 * 10^6 ) ≈ 26,306 mi
=======================================================
2. <span>∠BAC = 9°
</span>
<span> Δ ABC is a right triangle , ∠B = 90°</span>
<span> ∠CBA = 90°
</span>
∴ ∠BCA = 180° - (90° + 9°) = 81°
∴ the measure of arc BD which facing the <span>satellite = 2 * 81° = 162°
</span>
while the total angel of the circle = 360°
∴ <span>The percent of the Earth’s equator which is within range of the satellite’s signal = 162/360 = 0.45 = 45%

The measures of the angles are 59 degrees
<h3>How to determine the value of the angles?</h3>
The angles are given as:
Angle 1 = 2x + 17
Angle 2 = 3x - 4
By the interior angle theorem, the angles are congruent
So, we have
Angle 1 = Angle 2
Substitute the known values in the above equation
2x + 17= 3x - 4
Collect the like terms
3x - 2x = 17 + 4
Evaluate the like terms
x = 21
Substitute x = 21 in Angle 1 = 2x + 17
Angle 1 = 2 * 21 + 17
Evaluate
Angle 1 = 59
This means that
Angle 1 = Angle 2 = 59
Hence, the measures of the angles are 59 degrees
