Tanushree Bhosale 5 years, 9 months ago

As the opposite angles of a parallelogram are equal :- 2x+6 = 96-x Transfer -x to L.H.S and 6 to R.H.S 2x+x = 96-6 3x = 90 x = 90/ 3 x= 30 Therefore, the value of x is 30 degrees...

Sia ? 5 years, 9 months ago

Since, sides of coloured triangular wall are 15 m, 11 m and 6 m.
$\therefore$ Semi-perimeter of coloured triangular wall
S = $\frac{15+11+6}{2}$ = $\frac{32}{2}$ =16 m
Now, Using Heron’s formula,
Area of coloured triangular wall
= $\sqrt{s\left( s-a \right)\left( s-b \right)\left( s-c \right)}$
= $\sqrt{16\left( 16-15 \right)\left( 16-11 \right)\left( 16-6 \right)}$
= $\sqrt{16\times 1\times 5\times 10}$
= $20\sqrt{2}{{m}^{2}}$
Hence area painted in blue colour = $20\sqrt{2}{{m}^{2}}$

Angadh Kamboj 5 years, 9 months ago

First we find the semi perimeter of its all side that is S=a+b+c/2 S=15+11+6/2 S=32/2=26 So semi perimeter of all sides is 16 Now using herons formula Underroot s(s-a) (s-b) (s-c) Put the value 16(16-15) (16-11) (16-6) 16×1×5×10 These all are underroot Now take common from that What we can write to 16 4×4 So put 4×4×5× now expand 10 that is = 5×2 4×4×5×5×2 Now take 4 and 5 out of the root And 2 in root 4×5 underroot 2 that is 20 undertoot 2 cm²

Yogita Ingle 5 years, 9 months ago

Given, ∠ DAB + EBA = 180°. CA and CB are bisectors of ∠ DAB ∠ EBA respectively.
∴ ∠ DAC + ∠ CAB = 1/2 (∠ DAB).....(1)
⇒ ∠ EBC + ∠ CBA = 1/2 (∠ EBA)....(2)
⇒ ∠ DAB + ∠ EBA = 180°
⇒ 2 (∠ CAB) + 2 (∠ CBA) = 180° [using (1) and (2)]
⇒ ∠ CAB + ∠ CBA = 90°

In Δ ABC,

∠ CAB + ∠ CBA + ∠ ABC = 180° (Angle Sum property)
⇒ 90° + ∠ ABC = 180°
⇒ ∠ ABC = 180° - 90°⇒ ∠ ABC = 90°

(a+b+c)³ - a³-b³-c³ = [(a+b)+c]³ – a³-b³-c³

= (a+b)³+c³+3c(a+b)(a+b+c)-a³-b³-c³

= a³+b³+3ab(a+b)+c³+3c(a+b)(a+b+c)-a³-b³-c³

= a³+b³+c³+3ab(a+b)+3c(a+b)(a+b+c)-a³-b³-c³

= 3ab(a+b)+3c(a+b)(a+b+c) 3(a+b)[ab+c(a+b+c)]

= 3(a+b)[ab+ac+bc+c²] 3(a+b)[a(b+c)+c(b+c)]

= 3(a+b)(b+c)(c+a)

Posted by Ridhima Rana 5 years, 9 months ago

Sia ? 5 years, 9 months ago

In $\triangle$ ABC and $\triangle$ BAC
AD = BC [Given]
$\angle$ DAB = $\angle$ CBA [Given]
AB = AB [Common]
$\therefore \triangle ABD \cong \triangle BAC$ [By SAS congruency]
Since
ΔABD≅ΔBAC
$\therefore$ BD=AC[By C.P.C.T.]
Since
ΔABD≅ΔBAC $\triangle \mathrm{ABD} \cong \triangle \mathrm{BAC}$
$\therefore$ $\angle$ ABD = $\angle$ BAC [By C.P.C.T.]
