No you type the numbers press = and poof
It is true, how??Here is explanation:
Consider a quadrilateral ABCD .Join diagnol AC so two triangles ABC & ACD will form.
Sum of interior angles of ABC is 180 and that of ACD is 180 as well.So, the total sum of the interior angles of ABC & ACD is 360 which is the sum of interior angles of quadrilateral itself.
Answer:
in degree 11.54
in radians 0.20
Step-by-step explanation:
soh= o/h
sin(y)=4/20
y=sin^-1(4/20)
