Question

Solve the following ​

Answer 1

Answer:

65 and 65 E angle and F

Step-by-step explanation:

50+65+65 -180

Answer 2

Answer:

in ∆DEF <D =50° & DE= DF

Therefore, <DEF = <DFE

Hence, <DEF+<DFE+<D=180°

or, <DEF+<DFE = 180°-<D

or, <DEF + <DEF = 180°- 50° [as

<DEF =<DFE ]

or, 2<DEF = 130°

or, <DEF = 130°/2

= 65°

THEREFORE Angele E =65° and <F = 65°
