Let P be the mid point of the hypo. of the right triangle ABC, right angled at B.

Draw a line parallel to BC from P meeting AB at D.

Join PB.

in triangles,PAD and PBD,

angle PDA= angle PDB (90 each due toconv of mid point theorem)

PD=PD(common)

AD=DB( as D is mid point of AB)

so triangles PAD and PBD are congruent by SAS rule.

PA=PB(C.P.C.T.)

but

PA=PC(given as P is mid point )

So,

PA=PC=PB

please like my answer plzzzzzzzzz

Indicators are not affected by salt as salt is the product of acid and base which is neutral. Indicators are substances which gives a prominent sign to identify the presence of acids and alkali in the solution. Salt is produced from the reaction of acids and bases.

this is the correct answer for this question Thank you

Total numbers are 3 to 32=30

Prime numbers=3,5,7,11,13,17,19,23,29,31=10

Probability=10/30=1/3

option a is correct

C.P = xgain = 5 %

S.P = x+(5/100)x= x+(1/20)x= (21/20)x----------------------------Now if S.P were to be ₹490 less , then ;

S.P = (21/20)x - 490C.P = xLoss = 2 %

S.P = x - (2/100)x

(21/20)x - 490 = x - (1/50)x

(21/20)x + (49/50)x = 490

[ (105+98)/100 ] x = 490

x = 49000/203

x = 241.37----------------------------------------Hence the cost price of the Radio set is ₹ 241.37

Cost of 5m cloth=210RsCost of 1m cloth=210/5=42Rs

Cost of 2m cloth=2*42=84Rs

Cost of 4m cloth=4*42=168Rs

Cost of 10m cloth=10*42=420Rs

Cost of 13m cloth=13*42=546Rs

1) less than 5=1,2,3,4so probability = 4/40=0.12) Greater than 30 =31,32,33,34,35,36,37,38,39,40so probability = 10/40=0.253) Multiple of 5=5,10,15,20,25,30,35,40so probability=8/40=0.20

Given: ABCD is a quadrilateral in which P, Q, R and S are mid-points of the sides AB, BC, CD and DA.

AC is a diagonal.

To Prove: (1 SR || AC and SR = AC (2) PQ = SR (3) PQRS is a parallelogram.

Proof:(1) In Δ DAC,∴ S is the mid-point of DA and R is the mid-point of DC∴ SR || AC and SR = ½AC [Mid-point theorem]

(2) In Δ BAC,∴ P is the mid-point of AB and Q is the mid-point of BC∴ PQ || AC and PQ = ½AC [Mid-point theorem]But from (1) SR = AC∴ PQ = SR

(3)PQ || AC ..............From (2)SR || AC ..................From(1)∴ PQ || SR [Two lines parallel to the same line are parallel to each other]Also, PQ = SR ................From (2)∴ PQRS is a parallelogram.

Car Price = 350000Car price after first year= 350000(1 - 20/100)= 350000(4/5)= 70000*4 = 280000

Car price after second year= 280000(1 - 25/100)= 280000(3/4)= 210000

Car price after third year= 210000(1 - 25/100)= 210000(3/4)= 630000/4= 157500
