Question

Construct triangle LMN,in which angle M=60 degree, angle N=80 degree and LM+MN+NL=11CM

Answer 1

Step-by-step explanation:

Here we have to take sides such that their sum is 11, also it should satisfy the condition that sum of two sides in triangle is greater than third side

sides can be 5, 4 and 2

now angles of triangle is 80, 60 and 40

so 5 will be opposite to 80......side opp to greater angle is greater

4 opposite to 60

2 opposite to 40

so LM = 5 cm

LN = 4 cm

NM = 2 cm

construct the triangle
