A woman said to her to her son ," I was as old as you are now at the time of your birth". If the woman is 56 years old now, find her son's age 9 years ago

he son was 19

Step-by-step explanation:

if the son is the same age as his mom was when she gave birth to him you must divide the mothers ageby 2 so you get half her age which would be 28 then you subtract 9 and you get 19

56/2=28

28-9=19

i think he is 6 years and 2 months old

Step-by-step explanation:

29.5977692753

step-by-step explanation:

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.
