Question

[29-(-2) [6 (1.3)}] - [ 3x15 + (-3) X (-2)JJ : 21 a), o oro b)-I ac c)? d) b!O 214​

Answer 1

Step-by-step explanation:

Midpoint of B and C

(

2

λ−1

,4,

2

μ+2

)

Now, D.R.'s of median will be

(

2

λ−1

−2,4−3,

2

μ+2

−5) .

(

2

λ−5

,1,

2

μ−8

)

D.C.'s will be same since it is equally inclined to the coordinate axis.

2

λ−5

=1=

2

μ−8

⇒λ=7andμ=10

∴

λ

μ

=

7

10

Answer 2

Step-by-step explanation:

[29-(-2){6-(7-3)}]÷[3×{5+(-3)×(-2)}

= [29-(-2){6-(7-3)}]÷[3×{5+6}

= [29-(-2){6-(7-3)}]÷[3×11}

= [29-(-2){6-(7-3)}]÷[33}

= [29+2 {6-(7-3)}]÷[33}

= [29+2 {6-4}]÷[33}

= [29+2 {2}]÷[33}

= [29+4]÷[33}

= [33]÷[33}
