Find the unknown sides and angles of a rectangular rectangle from the following data hypotenuse c = 17, β = 34 ° 18 ‘.

Angle C will be 90 degrees.
We know the angle B = 34 degrees 18 minutes.
Then, according to the rule of the sum of the angles of a triangle, the angle A is equal to:
180 degrees – 90 degrees – 34 degrees 18 minutes = 56 degrees 42 minutes;
We find the side AC = AB * cos A = 17 * cos 56 degrees 42 min = 17 * 0.55 = 9.35cm;
Find the side CB = root of AB ^ 2 + AC ^ 2 = root of 17 ^ 2 + 9.35 ^ 2 = 14.2cm;
