Answer:
C) isosceles triangle
Step-by-step explanation:
equilateral triangle has all sides the same and all angles the same
180/3 = 60 so each angle is 60 degrees
A) obtuse triangle
means it has an angle bigger than 90 degrees
B) right triangle
that means it has an angle at 90 degrees
C) isosceles triangle
That means it has 2 sides that are the same
D) scalene triangle
that means it has no sides the same
If it has 3 sides the same. it must have 2 sides the same. So any equilateral triangle must be an isosceles triangle
The value of x is 36.
Solution:
Given angles of a triangle are 2x°, 2x° and x°.
To find the value of x:
<em>Sum of the all the angles of a triangle = 180°</em>
2x° + 2x° + x° = 180°
5x° = 180°
Divide by 5 on both sides of the equation.
x° = 36°
x = 36
The value of x is 36.
