Question

IF Δ ABC ~ Δ DEF and ∠A=450 ,∠E=800 then, ∠C=_________​

Answer 1

Answer:

hope this helps you

answer- 55°

Step-by-step explanation:

ABC. and DEF are congruent. Therefore there sides will also be equal.

So,

Angle a= angle d

angle b= angle e

angle c= angle f

given that

angle a = 45°

so angle d is also 45°

and angle e= 80°

so angle b is also 80°

from angle sum property

angle a+angle b+ angle c= 180°

45°+ 80° + angle c= 180°

angle c= 180°- 125°

angle c= 55°

therefore angle c = 55°
