Question

<ABC=28°
<C=(2x+13)°
x=?


​

Answer 1

Answer:

x=C-13/2

Step-by-step explanation:

<C=(2x+13°)

2x+13=C

2x=C-13

2x/2=C-13/2

x=C-13/2

x=C-13/2

Answer 2

Answer:

∠Inner side of ∠CDE = 360° - 249° = 111°

∠BCD and Innerside of ∠CDE are Supplimentary

So 2x + 13° = 111°

2x = 111° - 13° = 98°

$x = \frac{98}{2} = 49$

Therefore, x = 49°
