Help me on this question please!

256 cm^2

Step-by-step explanation:

2 of triangulars can be together to become a new square.

because these 2 triangulars have a symmetric shape.

So the all area is 10×16 (the square in the center) + (6×16)

All area is 160 + 96

= 256 cm^2

* the formular of the square area is the width × the length

y=1/4x-4

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.
