Answer:
43°
Step-by-step explanation:
The sum of all internal/interior angles of a triangle is always equal to 180°
Because of this, if the missing angle is x we can write the equation:
82°+55°+x=180° since the interior angles are given
Add like terms:
⇒ 137°+x=180°
Subtract 137:
⇒ x=43°
I want to say the slope of AC will be 0
one way to do this is to convert each fraction to same denominator ( the LCD)
Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.
4/7 = 16/28 and 3/4 = 21/28
so 4/7 < 3/4
Therfore 4/7 does lie between the 2 fractions
