Option A

Step-by-step explanation:

If two chords of a circle are intersecting each other inside the circle,

Measure of the angle formed between these chords is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

Therefore, m∠AEC = $\frac{1}{2}(\text{arcAC}+\text{arcBD)}$

m∠AEC = $\frac{1}{2}(110^{\circ}+40^{\circ})$

= 75°

Therefore, Option A will be the correct option.

Rationalize denominator in order to vanish radical term from denominator,

$\frac{7(5+ \sqrt{3})}{(5- \sqrt{3})(5+ \sqrt{3})} = \frac{7(5+ \sqrt{3}) }{25-3} = \frac{35+7 \sqrt{3} }{22}$
