Question

please gave me answer of this please write with solutions​

Answer 1

Answer:

Q.4.A). 1)using distance formula

$\sqrt{( {x2}^{2} - {x1}^{2}) + (y \ {2}^{2} - {y1}^{2} )}$

d=√(-5-7)^2+(1-(-4))^2

d=√(-12)^2+5^2

d=144+25

d=169 units

B) using section formula

(mx2+nx2/2 , my2+ny1/2)

in PTR

(1×2+1×3/2 , 1×(-5)+1×2/2)

(2+3/2 ,-5+2/2 )

(5/2 , -3/2)

R(5/2,-3/2)

inQTS

(1×2+1×1/2 , 1×(-5)+1×0/2)

(2+1/2 , -5/2)

(3/2 ,-5/2)

S (3/2 , -5/2)

C) using section formula

discuss above

(3×6+10×1/2 , 3×7+10×2/2)

(18+10/2, 21+20/2)

(180/2 , 420/2)

(90 , 210)

P(90,210)

for Q.D) Iam not sure about answer so.
