Two people can sit at the long side of a cafeteria table, and one person can sit at the short side, Tables are pushed together as shown to seat more
people. Arrangements for one and two tables are shown.
Make a chart to find how many tables need to be pushed together to seat 14
people,
A. 7 tables
OB. 4 tables
C. 6 tables
D. 5 tables

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.

207/8 is the right

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
