find x and y in the figure given above
Answers
Answer:
hey mate ✌✌
here,
x = 27⁰ ( alternate angle).✔
for y,
angle BCD = 27⁰(alternate angle)
angle ACB = 27⁰ + 25⁰ = 52⁰
we know, sum of angles of a triangle is 180⁰
y = 180⁰- ( 52 + 68)
y = 180 - 120
y = 60⁰✔

Given :-
- In ∆ABC , DE || BC.
- ∠AED = X°
- ∠ DAE = Y°
- ∠ABC = 68°
- ∠EDC = 27°
- ∠ECD = 25°
Solution :-
Since A-E-C is a Straight Line ,,
So,
→ ∠AED + ∠DEC = 180° (Linear Pair) .
→ x + ∠DEC = 180°
→ ∠DEC = (180° - x) ---------- Equation (1).

Now, in ∆DEC, we have :-
→ ∠EDC = 27°
→ ∠ECD = 25°
→ ∠DEC = (180° - x) (From Equation (1) )
we know That, Sum of All angles of a ∆ are 180° .
So,
→ ∠EDC + ∠ECD + ∠DEC = 180°
→ 27° + 25° + (180-x)° = 180°
→ 27° + 25° = 180° - 180° + x
→ x = 27° + 25°
→ x = 52° (Ans).
______________________________
Now in ∆ADE , we Have :-
→ ∠ADE + ∠DAE + ∠DEA = 180° (By Angle - sum Property).
Now, Given That, DE || BC ,
Hence,
→ ∠ADE = ∠ABC = 68°
→ ∠ADE = 68°
So,
→ ∠ADE + ∠DAE + ∠DEA = 180°
→ 68° + y° + x° = 180°
Putting value of x now, we get,
→ 68° + y° + 52° = 180°
→ y° = 180° - (68° + 52°)
→ y° = 180° - 120°
