The CENTRAL idea of the article is developed by . A explaining how long it can take to pay off a mortgage or student loan with different percentage rates of interest B contrasting the amount that an average percentage of sales tax costs on large and small purchases C arguing that banks should charge lower percentage interest rates on credit cards to help consumers D providing examples of common real-life situations that use percentages and how to calculate them

sss (side, side, side)

sas (side, angle, side)

asa (angle, side, angle)

aas (angle, angle, side)

hl (hypotenuse, leg)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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.

vertical=18cm horizontal=18cm hypotenuse=25.5
