Answer face for20 points!The square root of 144 is 12, because12 x 12 = 144. The square root of 169 is 13, because 13 x 13 = 169 Which expression will give the closest approximation to the square root of 156?

B.
169 - 144
13
2
C
+
D

9;144)

C

Step-by-step explanation:

Sq root of 156 HAS to be between 12 and 13

12+(13-12)/2

12+1/2

12.5

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.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
