X×y＝z
If z is an irrational number, it can be said that x and y are also irrational.
Hope my answer helped u :)
It would be A, Side Angle Side (SAS). Because you are given we congruent sides, and tow right angles. Using the reasoning of "If two two angles are both right angles then they are congruent" you can prove the angles congruent.
The reason it is not HL is because HL is used when it is given a right angle and the hypotenuse and one of the legs congruent. Therefore the only choice is Side Angle Side (SAS).
80/100 = 96/x
80x=9600
8x=960
x=120
120/4
30
so the answer is b
