A rectangle 5

A rectangle has sides of 10 cm and 14 cm. Calculate the angle between a diagonal and a long side.

Correct answer:

A =  35.5377 °

Step-by-step explanation:

a=10 cm b=14 cm  d=a2+b2=102+142=2 74 cm17.2047 cm  cosA=b:d  α=arccos(b/d)=arccos(14/17.2047)0.6202 rad  A=α=α 180π=0.6202 180π=35.538=35.5377=353216"
