Answer 1

Answer:

1. 9√5 (here √5 is common so we have to add only 4 and 5 no.)

2. option a) 26° is correct .

here, on ED there are two angles DCF and angle FCE.

So, angle DCF + angle FCE = 180° (linear pair)

62 + angle FCE = 180°

angle FCE = 180 - 62

angle FCE =118

therefore angle FCE is 118°

now ,

FCE + CEF + EFC = 180 ° ( angle sum property)

118 + 36 + x = 180

154 + x = 180

x. = 180 - 154

x = 26

therefore value of x is 26°

option a) 26° is correct .
