the measures of the angles of
△abc
are given by the expressions in the table.
angle
measure
a

(6x−1)°

b
20°
c
(x + 14)°
what are the measures of angles a and c?

enter your answers in the boxes.


m∠a=
º

m∠c=
º

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
