Answer:
- ∠BCA = 30°
- ∠FHC = 125°
- ∠A = 45°
- ∠GBC = 75°
- arc EBC = 260°
Step-by-step explanation:
Angle BCA intercepts arc FB, so is half its measure: 60°/2 = 30°.
Angle FHC is half the sum of the angles intercepted by its chords: (60°+150°+40°)/2 = 125°.
Angle A is half the difference of the arcs it intersects: (150° -60°)/2 = 45°.
Angle GBC is half the measure of the arc it intercepts: 150°/2 = 75°.
arc EBC is the sum of arcs EF, FB, and BC: 50° +60° +150° = 260°.
Answer:
x = -6
Step-by-step explanation:
-2x-14=-2
Add 14 to each side
-2x-14+14=-2+14
-2x = 12
Divide by -2
-2x/-2 = 12/-2
x = -6
