<span>In a triangle, the three interior angles always add to 180°.
56° + 72° + x° = 180°
128° + x° = 180° |subtract 128° from both sides
x° = 52°</span>
formula for generating Pythagorean Triples (where m>n>0):
x=2mn
y=m²-n²
z=m²+n²

Answer:
Y=60
Step-by-step explanation:
S+Y=90
S=(2*Y)-90
Y+2Y-90=90
3Y=180
Y=60
Plug back into S+Y=90
S+60=90
S=30
