Scientists believe there is a link between ambient temperature and damage to a head gasket on a car. they perform a study recording daily temperature and the damage index to a head gasket on a car. what is the domain? a) temperature b) type of car c) damage index d) mileage on car

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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.

13.46

step-by-step explanation:

16.80 x .20 = 13.46
