Answer 1

Answer:

$\huge\pink{\mid{ \underline{ \overline{ \tt AnswER }} \mid}}$

∠GEF=180−∠CEF

(∵∠GEF and ∠CEF are complementary angles)

∴∠GEF=30°

and ∠GCD=∠GEF (from the figure, CD∣∣EF)

⇒∠GCD=30°

Now, ∠BCD=∠BCG+∠GCD

⇒∠BCD=25° +30°

=55°

∠ABC=∠BCD(∵AB∣∣CD)

∠ABC = x = 55°

Therefore the value of x is 55.
