Step-by-step explanation:
• When two secants intersect a circle the measure of the angle between them is half the difference of the intercepted arcs. Tangent DH is a degenerate case of a secant in which both points of intersection are the same point (D). Thus ∠GHD is half the difference of arc GD and ED.
• We assume points B and C are on radii DA and EA, respectively. Hence arc DE has the same measure as ∠BAC, and ∠DGE has half that measure.
• Tangent DH will intersect radius DA at right angles. Hence ∠ADH = 90°.
• ∠DHE = ∠DHG, whose measure is given by the formula in the first answer choice. The formula in the 4th choice is different (and wrong).
• ∠DGE and ∠BFC both intercept arcs with the same measure. Neither is greater than the other: they are equal in measure.
• Inscribed triangle DGE cannot be a right triangle because none of its sides is a diameter of the circumcircle.
A family with no children will work because each boy has 0 sisters and 0 brothers and the girls have 2 times as many brothers as sisters because 2 times 0 is still 0.
It also works in a family with 4 boys 3 girls
each boy has 3 brothers and 3 sisters and the sisters have 4 brothers and 2 sisters
