-6.4(x-2.25)=19.2 
-6.4*x=-6.4x   -6.4*-2.25=14.4
rewrite
-6.4+14.4=19.2 subtrac 14.4 from both sides 19.2-14.4=4.8 rewrite
-6.4x=4.8 divide -6.4 from both sides 4.8/-6.4=.75
x=0.75

The measure of an angle is three more than twice its supplement. What is the measure of the angle?
Zinaida [17]

Answer: the angle is 1°+n×120°

1°, 121°, 241°


Step-by-step explanation:

Angles are taken modulo 360°, so 363° = 3°.

Angle plus supplement gives 180°.

Let a be angle, s be supplement of a.

So s = 180-a. Given a = 3 + 2s

a = 3 + 2(180 - a)

a = 3 + 360 - 2a = 363 - 2a


3a = 363° or 3° or 723°

a = 121° or 1° or 241°


a = 1°

s = 179°

2s = 358°

2s+3 = 361° = 1° (modulo 360)


a = 121°

s = 180-121 = 59°

2s = 118°

2s + 3 = 121°, as required.


a = 241°

s = 360+180-241 = 540-241 = 299

2s = 598

2s + 3 = 601 = 241 (modulo 360)
