Answer:
<J = 45
<L = 45
<M = 90
This is an isosceles right triangle
Step-by-step explanation:
The angles of a triangle add up to 180 degrees
<J + <L + <M = 180
2x+15 + 5x-30 + 6x = 180
Combine like terms
13x -15 = 180
Add 15 to each side
13x-15+15 = 180+15
13x = 195
Divide each side by 13
13x/13 =195/13
x =15
<J =2x+15 = 2*15+15 = 30+15 = 45
<L = 5x-30 = 5*15 -30 = 75-30 = 45
<M = 6*15 = 90
The triangle is a right triangle
Since two angles are equal, that means two sides are equal so it is an isosceles triangle.

The correct option is D for the placement of regular polygon and the rhombus.
<h3>What is defined as the
regular polygon?</h3>
- A polygon is a two-dimensional enclosed image created by connecting three or more straight lines.
- A rhombus is a special parallelogram because it meets the definition of a parallelogram, which is a quadrilateral to two pairs of parallel sides.
- A polygon is made up of three parts:
- Sides: A side is a line segment that connects two vertices.
- Vertices: A vertex is the point where two sides meet.
- Interior and exterior angles An interior angle is an angle formed by joining the sides of a polygon within its enclosed surface.
As, all the given figures comes under the regular polygon, all are placed in the left circle.
But the three diagram in white, orange and blue colour are regular polygon along with rhombus.
Thus, all three are placed in the intersection of the both circle of the vein diagram.
