they add up to 180 so it depends. you have to know one of the measures
An angle which has measure between 90 degrees and 180 degrees is an obtuse angle.
Complementary.
it should be 169
Let the angle = θLet the height = aLet the base = b* means multiplied byIf the angle touches the base:tanθ = a/bb = a/tanθIf the angle touches the height:tanθ = b/ab = a*tanθWhen transferring the second line of working (b= ...) into a calculator, replace a with the height and θ with the angle. The answer will be b.
