SSC CHSL - 13th October 2020 - Shift 1 • Quantitative Aptitude • Q57

If in the given figure, ∠ACB + ∠BAC = 80o; ∠BDE = 35o; ∠BCE = 45o , then the marked angle ∠CED is:

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e 160o

Understanding Application

We will use the property of exterior angle in which the exterior angle of a triangle is equal to the sum of the interior opposite angles.

We have given that

∠ACB + ∠BAC = 80o

∠BDE = 35o

∠BCE = 45o

We will join E to F which will be as

⇒∠DBC = ∠ACB + ∠BAC 

⇒ ∠DBC = 80o

⇒ ∠CFD = 125o

⇒ ∠CED = 125 + 35 = 160o
