What are the dimensions of a 40-inch (diagonal) 4:3 television?

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.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

the answer to this is a. a^2 + b^2 = c^2

to be honest i don't know but i need points so
