Question

if triangle ABC~triangleDEFand angle A=45degree,LE=87degree then LC=?​

Answer 1

Triangle ABC

A = 45

LE = 87

LC = ?

We can find the solution by using Angle sum property.

As we already know that sum of interior angles of a triangle is 180 Degrees.

So,

LC = 180 - (87+45)

     = 48

To confirm we can add al the angles and check if they sum up to 180.

87+45 + 48 = 180

Hope this helps
