Answer:
∠BFA = 50°
Step-by-step explanation:
To find∠ BFA we first have to find ∠BFE this is how we'll do it!
5x-10 + 3x+4 + 2x +16 = 180 (collect like terms)(5x+3x+2x)(-10+4+16)
10x + 10 = 180 (minus 10 on each side)
10x = 170 (divide by 10 on each side)
x = 17
Plug in. (Plug in the rest of the equations)
5(17)-10=75°
3(17)+4=55°
2(17)+16=50°
∠BFA would equal 50 degrees because it is vertical of ∠DFE.
When two angles are vertical to each other they equal the same amount or in other words they're congruent.
Hope this helps!!!
