The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees?

The smallest angle is 40.

Step-by-step explanation:

2x-6+3x+5+2x+20=180

7x+19=180

7x=180-19

7x=161

x=161/7

x=23

Now,

= 2x-6

= 2×23-6

= 40

= 3x+5

= 3×23+5

=74

=2x+20

=2×23+20

=66

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
