Question

In the village of Surya, there was a big pole PC as shown in the figure. This pole was tied to a

strong wire of 10m length. Once there was a big spark on this pole, thus wire got damaged verybadly. Any small fault was usually unrepaired with the help of a rope which normal board

electricians were carrying on bicycles. This time electricians need a staircase of 10m so that it

can reach at point P on the pole and this should make 600 with line AC. Answer the following

questions:

(i) In the ∆PAC and ∆PBC which side is common?

(a) PC (b) AB (c) AC (d) BC

(ii) In the ∆PAC and ∆PBC which angles are given to be equal?

(a) ∠A = ∠x

(b) ∠B = ∠x

(c) ∠B = ∠y

(d) None

(iii)In the figure ∆PAC and ∆PBC are congruent due to which criteria?

(a) RHS

(b) SAS

(c) SSS

(d) ASA

(iv) What is the value of <PBC?

(a) 300

(b) 600

(c) 900

(d) 450

(v) What is the value of<X?

(a)300

(b) 600

(c) 450

(d) 900​
