Step 1
Given,
a right angle triangle
E=90
ED=6
EF=3
Step 2
Let F=θ
then tanθ=pb=DEEF
tanθ=63
tanθ=2
θ=tan12
θ=63.434
=63.4
 on F=63.4

Step 1
b=6
c=3
α=90
Step 2
a2=b2+c22bccosα
a=b2+c22bccosα
a=62+322×6×3×cos90
a=6.71
Step 3
a=6.71
b=6
c=30
a2=b2+c22bccosα
α=arccos(b2+c2a22bc)=arccos(62+326.7122×6×3)=90
b2=a2+c22accosβ
β=arccos(a2+c2b22ac)=arccos(6.712+32622×6.71×3)=63
Answer: mF=63
