The right triangle

In the right triangle ABC with a right angle at C, we know the side lengths AC = 9 cm and BC = 7 cm. Calculate the length of the remaining side of the triangle and the size of all angles.

Correct answer:

c =  11.4018 cm
A =  37.875 °
B =  52.125 °

Step-by-step explanation:

b=9 cm a=7 cm c2 = a2+b2  c=a2+b2=72+92=130=11.4018 cm
sin A = a/c  A=π180°arcsin(a/c)=π180°arcsin(7/11.4018)=37.875=37°5230"
