Answer: B, Each of the sums is 180 degrees.
Step-by-step explanation:
Since a 180 degree angle is always a flat line, and that is the case for this,
Each of the sums is 180 degrees.
Answer:
Step-by-step explanation:
-16-16v - v = 10v + 4
Add 16 to both sides and combine like terms giving you
15v = 10v + 20
Subtract 10v from both sides
5v= 20
Divide by 5
V=4
Get the x variable on one side and the numbers another side.
9/10(x + 2/3) = 4 1/2
Distribute the 9/10 across the x and 2/3.
(9/10)x + 18/30 = 4 1/2
Simplify 18/30 to make our life easier.
(9/10)x + 3/5 = 4 1/2
Subtract 3/5 from each side of the equation.
(9/10)x = 3 9/10
Divide both sides by 9/10.
x = 4 1/3
It would have to be an obtuse triangle
