Answer:

Step-by-step explanation:
as if we form an imaginary triangle with this line as hypotenuse
we get
- base = 3 units
- perpendicular = 4 units
using Pythagoras theorem:-
hyponteuse ² = perpendicular ² + base²
hyp² = 4² + 3²
hyp² = 16 + 9

hyp = 5 units

Perceent means parts out of 100
x%=x/100
30/100=30%
Angle Q and angle S equal 61
