well, im assuming its talking about a triangle. The total number of degrees is 180. I guess you subtract that by 81. You get 99. But there are still the others. Srry this is how far i can help. But you then go with 99 and divide or sum thing.
QP = (8, 9) and | QP | = √145
QP = p - q = (7, 16 ) - ( - 1,7) = ( 7 + 1, 16 - 7) = (8, 9)
given a vector (x , y) then magnitude = √x² + y²
|QP | = | 8² + 9² = √145

Answer:
the answer is B
Step-by-step explanation
Cant really explain but next time put the topic for the subject so people will understand.
Multiply 5.8 by 100 to convert to percent:
<span>5.8 × 100 = </span>580 %
