Answer:
m<GFC = 149°
Step-by-step explanation:
m<GFC = m<C + m<CDF (exterior angle theorem)
Substitute
12x - 7 = 26 + 8x + 19
Subtract 8x from each side
12x - 7 - 8x = 26 + 8x + 19 - 8x
4x - 7 = 26 + 19
4x - 7 = 45
Add 7 to both sides
4x - 7 + 7 = 45 + 7
4x = 52
Divide both sides by 4
4x/4 = 52/4
x = 13
✔️m<GFC = 12x - 7
Plug in the value of x
m<GFC = 12(13) - 7 = 149°
Answer:
14 years old
Step-by-step explanation:
let x= Xavier’s age
let y= Madeline’s age
Use linear function:
x+y=28
x=1/2y + 4
x+y=28
x-1/2y=4
Multiply 2nd equation by 2
x+y=28
2x-y=8
Add
3x=36
x=12
12+2=14
y=16
It would be 3 :) hope this helps
