Answer: 62°
Step-by-step explanation:
Total angle in a triangle = 180°
40° + 78° + < N = 180°
118° + <N =180
<N = 180 -118
<N=62°
-3x+20=2
move +20 to the other side
sign changes from +20 to -20
-3x+20-20= 2-20
-3x= 2-20
-3x= -18
divide both sides by -3
to get +x and x by itself
-3x/-3= -18/-3
Answer:
x= 6
