Question

Q6. यदि ABC तथा DEF समातर त्रिभुज है और कोण A= 45 तो कोण Dज्ञात कीजिये​

Answer 1

Answer: Step-by-step explanation:

We are given that triangle ABC is similar to triangle DEF such that angle A = 45 degrees and Angle B = 56 degrees.  

And we have to find the value of angle C.  

Since ABC ~ DEF, this means that;  

A = D,  B = E  and  C = F  

As we know that the angle sum property of the triangle says: The sum of all angles of the triangle is equal to 180°.  

So, In ABC,  

A + B + C = 180°  

Here we are given A = 45° and B = 56°, that means;  

45° + 56° + C = 180°  

101° + C = 180°  

C = 180° - 101° = 79°.
