S. When coffee beans are dried, the mass
decreases
in the ratio 5:13. Find the mass
of green coffee beans which must be
dried to
give 750kg of dry coffee bean:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

translate k to n and reflect across the line containing jk.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
