Question

Identify the measure of arc BG◠. HELP ASAP!! I'm so confused!

Answer 1

Answer:

arc BG = 14°

Step-by-step explanation:

∠BMG = $\frac{1}{2}$ ( arc BG + arc JS) = 30

Multiply both sides by 2

arc BG + arc JS = 60, that is

arc BG + 46° = 60° ( subtract 46° from both sides )

arc BG = 14°

Answer 2

Answer:

arc BG= 14°

Step-by-step explanation:

It is given in the figure that  mJS = 46∘ and m∠BMG = 30∘.

If two chords intersect in the interior of a circle, then the measure of each angle formed is half the sum of the measures of its intercepted arcs. So,  

m∠BMG = 12 (mJS +mBG)

Substitute the given values and solve for mBG.

30∘ = 12 (46∘ + mBG)

Multiply by 2.

60∘ = (46∘ + mBG)

Subtract 46∘.

14∘ = mBG

Therefore, mBG = 14∘.
