Question 747456
Triangle with an angle of 3 degrees means you have also an angle of 87 degrees.  If the 3 degree angle is opposite of the 70 cm. side, then you have the one other leg and the hypotenuse which you can find values using law of sines.  


Opposte of 90 degress_____________hypotenuse = h
Opposite of 3 degress_____________short leg = 70 cm.
Oppossite of 87 degrees___________long leg = y


{{{y/sin(87)=70/sin(3)}}}
{{{highlight(y=70*sin(87)/sin(3))}}}


{{{h/sin(90)=70/sin(3)}}}
{{{highlight(h=70*sin(90)/sin(3))}}}
