Five girls and five boys need to line up for a photo. the photographer wants them to be alternating boy, girl, boy, girl etc. what is the probability that the children will line up so that the photographer will be happy?

   Boy, girl, boy, girl, boy, girl, boy, girl, boy, girl

Step-by-step explanation:

The photographer wants them to be alternating boy, girl, boy girl, etc, so that's why this answer is correct.

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.
