In the exploratory chalenge, we drew the image of a general rotation/dilation of the unit square −b
b a

a. calculate the area of the image by enclosing the image in a rectangle and subtracting the area of the
surounding right triangles. show your work.
b. confirm the area using the determinant of the resulting matrix.

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.
