Area = 0.5*AB*BC*sin(ABC)
= 0.5*(2x+1)*(x+2)*0.5 = 3
So, (2x+1)*(x+2) = 12
2x2 + 5x + 2 = 12
2x2 + 5x - 10 = 0
x = 1.31 (to 3 sf)
Triangle A is the only possible name from the information provided.
Another name is its correct name: an isosceles triangle.
Using Pythagoras' Theorem: 35.56683849 units or 36 units which is correct to 2 significant figures.
Correct as would be the case for an isosceles triangle or an equilateral triangle
which is the correct product of the significant figures 3.278 and 4.23.
Correct
I believe you need 2 pieces of data (either an angle or another length) before you can calculate anything about the triangle. Anyone else can correct me if I'm wrong.
Correct; sum of angles of a triangle is 180 degrees.
It is an equiangular triangle it is correct.
Triangle A is the only possible name from the information provided.
A triangle in which no sides are the same lengthA scalene triangle is a triangle in whichall three sides have different lengths.
Using Pythagoras' Theorem: 35.56683849 units or 36 units which is correct to 2 significant figures.
That is correct
Another name is its correct name: an isosceles triangle.
I suspect that the correct name is TRIANGLE (with an A).
which is the correct product of the significant figures 3.278 and 4.23.
There are four different types of triangles. They include the isosceles triangle, equilateral triangle, scalene triangle and obtuse triangle. Triangles are used in geometry.
