Question

If ∆ABC and ∆ DEF are similar triangles such that ∠A= 57 and ∠E= 63, ∠C=?

Answer 1

Answer:

angleC=60

Step-by-step explanation:

ABC and DEF are similar

so,

angle E=angle B

so,angleB=63

now,

In triangle ABC

angleA+angleB+angleC=180

57+63+angleC=180

120+angleC=180

angleC=180-120

angleC=60
