2.	Factorize x3+13n2+32n+20
Answer» Answer: $x^3+13n^2+32n+20\\x^3+n(13n+32)+20\\$ It cannot be FUTHER FACTORED, but if you're LOOKING for $x^3+13x^2+32x+20$ It can be factored using the Rational ROOT Theorem $\frac{x^3+13x^2+32x+20}{x+1}=x^2+\frac{12x^2+32x+20}{x+1}$ $=x^2+12x+\frac{20x+20}{x+1}$ $=x^2+12x+20$ $=\left(x+1\right)\left(x+2\right)\left(x+10\right)$

2.

Factorize x3+13n2+32n+20

Answer»

Answer:

$x^3+13n^2+32n+20\\x^3+n(13n+32)+20\\$

It cannot be FUTHER FACTORED, but if you're LOOKING for $x^3+13x^2+32x+20$

It can be factored using the Rational ROOT Theorem

$\frac{x^3+13x^2+32x+20}{x+1}=x^2+\frac{12x^2+32x+20}{x+1}$

$=x^2+12x+\frac{20x+20}{x+1}$

$=x^2+12x+20$

$=\left(x+1\right)\left(x+2\right)\left(x+10\right)$

AREA of each clothes = 5×(area of 1triangle) a=50cm b=20cm c=50cm s=a+b+c÷2=50+20+50÷2=60cm area of triangle = $\sqrt{s(s - a)(s - b)(s - c)}$ $\sqrt{60(60 - 50)(60 - 20)(60 - 50)}$ $\sqrt{60 \times (10) \times (40) \times (10)}$ $\sqrt{6 \times 4 \times (10 { {}^{} }^{4} })$ $\sqrt{6 \times( 2 {}^{2} } )\times( 10 {}^{4} )$ $\sqrt{6 \times } \sqrt{2 {}^{2} } \times \sqrt{10 {}^{4} }$ $\sqrt{6} \times 2 \times 10 {}^{2}$ $200 \sqrt{6}$

An umbrella is made by stitching 10 triangular pieces of cloth of two different colours ,each piece measuring 20cm,50 cm and 50 cm.How much cloth of eachbcolouris required for the umbrella

Answer»

Step-by-step explanation:

there are 10 triangles.

Let 5 are BLUE and 5 are yellow.

AREA of each clothes = 5×(area of 1triangle)

a=50cm b=20cm c=50cm

s=a+b+c÷2=50+20+50÷2=60cm

area of triangle =

$\sqrt{s(s - a)(s - b)(s - c)}$

$\sqrt{60(60 - 50)(60 - 20)(60 - 50)}$

$\sqrt{60 \times (10) \times (40) \times (10)}$

$\sqrt{6 \times 4 \times (10 { {}^{} }^{4} })$

$\sqrt{6 \times( 2 {}^{2} } )\times( 10 {}^{4} )$

$\sqrt{6 \times } \sqrt{2 {}^{2} } \times \sqrt{10 {}^{4} }$

$\sqrt{6} \times 2 \times 10 {}^{2}$

$200 \sqrt{6}$

A triangle PQR prove that sum of its angle = 180 degree Answer Fast

Answer»

$\huge{\bf{\underline{\purple{Answer :}}}}$

$\bold{\red{Angle \ sum \ Property \ of \ triangle :-}}}$

⇒The sum of three angles of a triangle is 180° and this property of triangle is called Angle sum Property of Triangle .

$\rule{200}2$

GIVEN,

PQR is a triangle

To Prove ,

∠P + ∠Q + ∠R = 180°

Construction,

Extend QR to the POINT M . At the point R , draw RN || PQ

Proof,

⇒PQ||NR And PR is transversal

Therefore,

$\implies \bold{\angle QPR = \angle PRN }$ ................. 1) ( by ALTERNATIVE interior angle )

⇒PQ||NR and QM is the transversal .

Therefore,

$\implies \bold{ \angle PQR = \angle NRM}$ ................. 2) ( by Corresponding Angle)

From the According to Figure Construction :-

$\implies \bold{\angle PRQ + \angle PRN + \angle NRM = 180^{\circ}}$ ............(by Linear pair )

Now From first and Second Equation :

$\implies \bold{\angle P + \angle Q + \angle R = 180^{\circ}}$

Hence Proved
