All of the following amounts are excluded from gross income, except: a. Veterans' benefits b. Scholarship grants for tuition c. Gifts d. Tips and gratuities e. Child support payments

d. Tips and gratuities

Explanation:

Tips and Gratuities are not excluded from gross profit liable to tax. Tips serves as an additional income gotten as a result of you being a worker in an organization. It is an extra salary income.

Gratuity refers to the lump sum of money gotten after retirement. they are both included while calculating gross income.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
