Answer: 20 ;)
Step-by-step explanation:
No. Just because the angles are all less than 90 degrees, that doesn't tell us anything about the sides. The sides are all congruent ONLY if all 3 angles are 60 degrees each. If the angles all have different sizes, then so do the sides.
I have the same question that i don’t understand sorry i’m commenting so i can see if anyone else gets that answer
Answer:
Hence as long as x > 2/3, we can form a triangle from the three given sides.
Step-by-step explanation:
Given:
Length of 3 sides of triangle are 
Solution:
From the length of the 2nd side 4x, we know that x > 0
Let this be 1 st statement.
Now from the triangle inequality we can say that;

No new information from this because of the 1st statement above.
Also,

Lastly,

and again no new information is obtained from this inequality.
Hence as long as x > 2/3, we can form a triangle from the three given sides.
Using the y = mx + b formula
C = 225s + 3500
Then to transport 19 tons
C = 225(19) + 3500
C = 4275 + 3500
C = 7775
