Answer:
C. QR = 2 • PR
Step-by-step explanation:
According to given information we can draw a right triangle with angle measures as follows :
30-60-90 and for this special right triangle the side length would follow as:
The side length that sees angle measure 30 = a
The side length that sees angle measure 60 = a[tex]\sqrt{3}[/tex]
The side length that sees angle measure 90 = 2a
following this information the:
PR(sees 30 degrees) = a (can be represented as PR in this case)
and so
QR(sees 90 degrees) = 2a (2*PR in this case)
PQ(sees 60 degrees) = a[tex]\sqrt{3}[/tex] ([tex]\sqrt{3}[/tex] *PQ in this case)
The correct option is C. QR = 2 • PR
