Answer 2

1)

In ∆ TNM & ∆ TNS,

∠TNM = ∠TNS (Right angles)

TM = TS ( given)

TN = TN (common)

∴ ∆ TNM ≅ ∆ TNS, by RHS congruency.

2)

Let the Joseph's weight be x.

Younger brother's weight = x/2

According to question,

x + x/2 = 63

2x + x = 126

3x = 126

x = 42

∴ Joseph's weight is 42 kg.

3)

$\frac{ {x}^{2} + 4x + 4 }{x + 2} \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ = \frac{ {(x)}^{2} + 2(x)(2) + {(2)}^{2} }{x + 2} \\ \\ = \frac{ {(x +2 )}^{2} }{x + 2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ = x + 2\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

4)

5(1 - 2x) = 9(1 - x)

5- 10x = 9- 9x

5-9 = -9x +10x

-4 = x

∴ x = -4

5) ∆BAC ≅ ∆XYZ

Congruent sides -

AB = YX

AC = YZ

BC = XZ

Congruent angles-

∠BAC = ∠XYZ

∠ABC = ∠YXZ

∠ACB = ∠YZX
