Answer:
Hence the correct option is the last one . The triangle is an obtuse angled triangle.
Step-by-step explanation:
i) the sum of any two sides added together is greater than the third side hence this is a triangle.
ii) it is<em><u> not</u></em> a right angled triangle as and
iii) the triangle is not acute from ii) above
iv) the triangle is an obtuse triangle from ii) above.
Given:
In an isosceles triangle LMN, LM=MN.
To find:
The measure of the angles L, M and N.
Solution:
In triangle LMN,
(Given)
(Base angles of an isosceles triangle are equal)
Now,
On further simplification, we get
The value of x is 13. Using this value, we get
Similarly,
And,
Therefore, the measure of angles are .
