Check the picture below.
let's recall that a straight-line has 180°, and that sum of all interior angles in a triangle is also 180°.
Answer:
Its slope is
m = -1/(1/2) = -2
y = -2x + b
Get b from the given point.
-4 = -2(6) + b
b = 8
y = -2x + 8
Step-by-step explanation:
The degree is 138! Supplementary is 180 total
Thank you sooo I need this your a true life saver !
We have three sides in this triangle,
first side=2x
second side=x
third side=x+6
Perimeter of a triangle=sum of all sides.
Then, we can suggest this equation:
(2x)+x+(x+6)=62
4x+6=62
4x=62-6
4x=56
x=56/4
x=14
first side=2x=2(14)=28 cm
second side=14 cm
third side=x+6=14+6=20 cm
The length of the sides would be: 28 cm, 14 cm and 20 cm.
