Answer:

mFE = 119°

Explanation:

mGB = 90°

mGB = mBD

∴ mGD = 180°

⇒ mFE = 180 - (mDE + mFG)

mFE = 180 - (49 + 12)

mFE = 180 - 61

mFE = 119°

Answer:

119°

Step-by-step explanation:

[tex] In\: \odot A, [/tex] GD is diameter.

[tex] \therefore m\widehat{GFD} = 180\degree [/tex]

[tex] \because m\widehat {FG} +m\widehat {DE} = m\widehat {FE} \widehat{GFD} [/tex]

[tex] \therefore m\widehat {FG} +m\widehat {DE} + m\widehat {FE} = 180\degree [/tex]

[tex] \therefore 49\degree +12\degree + m\widehat {FE} = 180\degree [/tex]

[tex] \therefore 61\degree + m\widehat {FE} = 180\degree [/tex]

[tex] \therefore m\widehat {FE} = 180\degree - 61\degree [/tex]

[tex] \therefore m\widehat {FE} = 119\degree [/tex]
