Equilateral means that the 3 sides are equal length. For this to happen, the triangle needs to also have 3 equal angles, but it is mentionned that it has an obtus angle, therefore, not all angles are the same, meaning the 3 sides also aren't equivalent.
the triangle isn't equilateral
Answer:
B
Step-by-step explanation:
Answer:
Step-by-step explanation:
Hello there!
We can solve for x using law of sines
As we can see in the image a side length divided by sin ( its opposite angle) = a different side length divided by sin ( its opposite angle)
So we can use this equation to solve for x
Our objective is to isolate the variable using inverse operations so to get rid of sin (65) we multiply each side by sin (65)
we're left with
assuming we have to round the answer would be 33.18 or 33.2
In order to find all of these, you first must convert the percentage to a decimal. This would be 13% to 0.13.
Now, multiply 0.13 by all of these into a calculator.
1800 • 0.13 = 234
950 • 0.13 = 123.50
2200 • 0.13 = 286
3000 • 0.13 = 390
2600 • 0.13 = 338
