a=45
b=45
c=169
Explanation:
In order to get angles A and B , you have to know that all triangles add up to 180. If you have a right angle, you know that its 90 degrees. Subtract 180-90= 90
Since you have two angles you divide 90/2 which equals 45 , thus making angle A=45 and angle B=45
To get C remember that a^2+b^2=c^2
so 2^2 + 3^2= 169
