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?
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
