Answer:
Step-by-step explanation:
Hypotenuse squared = one leg square plus the other leg squared.
H^2=L1^2+L2^2
L2^2=H^2-L1^2
L2^2=14^2-3^2
L2^2=196-9
L^2=187
L2=√187
L2=13.7
L2 is approximately equals to 14
Only one triangle because 70+30+80=180 and 1 triangle has in total 180°
Your gonna wanna multiple (5/8)(5/8) which is 25/64 or about 39 percent. (I might not be entirely right, sorry. )
