Answer:
perpendicular(p)=5
base(b)=12
hypotenuese(h)=?
using pytha goras theorem,
h^2=P^2+b^2
h^2=(5)^2+(12)^2
h^2=25+144
h^2=169
h^2=13^2
h=13.
Answer:

Step-by-step explanation:
To convert from degree to radian measure
radian measure = degree measure × 
Hence
radian measure = 225 ×
=
= 
The ratios are both identical
sin x = perpendicular/hypotenuse = 3/5
cosy = base/hypotenuse = 3/5
