C
(x + 14)°

m∠A=
​º
​
m∠C=
​º

Respuesta :

all angles of a triangle added together equal 180 degrees
180=(6x-1)+(x+14)+(20) which simplifies to 180=7x+33
next, solve for x by subtracting 33
147=7x
then solve by dividing by 7
21=x
plug x back into your original equations to find the angle measures
A=6(21)-1   A=125 degrees
B=(21)+14    B=35 degrees
