Answer 1

Step-by-step explanation:

1. cost of 3 doors and 36 eggs=Rs90

cost of one egg = 90)36=Rs 2.5

now cost of 8 egg = 8×2.5=Rs20

2. in triangle PQS

and triangle QPR

PS =OR(given)

angle QPS= PQR=90°

SQ=SQ(common side)

PQS is congruent to triangle QPR

3.a) 8.3×10^-4

b) 3.05×10000000

0.000000305

c)

Answer 2

Step-by-step explanation:

13) there are rules to be congruent for two triangle. one of them is SSA (side side angle). two side and one angle has to be same for two triangles.

hare in the figure ∆PRQ and∆PSQ -

PS=QR, (mentioned)

PQ is a common side,

/_QSP = /_PRQ (both are right angle)

So, we can say ∆PRQ is congruent to ∆QPR.
