5.	if D is the mid point of hypotenuse AC of a right angled triangle ABC . write the value of BD in term of AC
Answer» Answer: LET ∆ABC is a right TRIANGLE such that ∠B = 900 and D is mid point of AC we produce BD to E such that BD = AC and EC. Now is ∆ADB and ∆CDE we have AD = DC [Given] BD = DE [By construction] And, ∠ADB = ∠CDE [Vertically opposite angles] ∴ By SAS criterion of congruence we have ∆ADB ≅ ∆CDE ⇒ EC = AB and ∠CED = ∠ABD ....(i) [By cpctc] But ∠CED & ∠ABD are alternate interior angles ∴ CE ║ AB ⇒ ∠ABC + ∠ECB = 1800 [Consecutive interior angles] ⇒ 90 + ∠ECB = 1800 ⇒ ∠ECB = 900 Now, In ∆ABC & ∆ECB we have AB = EC [By (i)] BC = BC [Common] And, ∠ABC = ∠ECB = 900 ∴ BY SAS criterion of congruence ∆ABC ≅ ∆ECB ⇒ AC = EB [By cpctc] ⇒ 1/2 AC = 1/2 EB ⇒ BD = 1/2 AC Step-by-step explanation: pls mark me the BRAINLIEST

5.

if D is the mid point of hypotenuse AC of a right angled triangle ABC . write the value of BD in term of AC

Answer»

Answer:

LET ∆ABC is a right TRIANGLE such that ∠B = 900 and D is mid point of AC

we produce BD to E such that BD = AC and EC.

Now is ∆ADB and ∆CDE we have AD = DC [Given]

BD = DE [By construction]

And, ∠ADB = ∠CDE [Vertically opposite angles]

∴ By SAS criterion of congruence we have ∆ADB ≅ ∆CDE ⇒ EC = AB and ∠CED = ∠ABD ....(i) [By cpctc] But ∠CED & ∠ABD are alternate interior angles ∴ CE ║ AB ⇒ ∠ABC + ∠ECB = 1800 [Consecutive interior angles] ⇒ 90 + ∠ECB = 1800 ⇒ ∠ECB = 900 Now, In ∆ABC & ∆ECB we have AB = EC [By (i)] BC = BC [Common] And, ∠ABC = ∠ECB = 900 ∴ BY SAS criterion of congruence ∆ABC ≅ ∆ECB ⇒ AC = EB [By cpctc] ⇒ 1/2 AC = 1/2 EB ⇒ BD = 1/2 AC

10. The ratio of the length of a school ground to its width is 5: 2. Find its length if the width is 40 metres.

Answer»

Given

The RATIO of the length of a school GROUND to its width is 5: 2.
Width of the ground = 40 m

To find

Length of the ground.

Solution

Let the ratio be X.

Then

$\sf\pink{⟶}$ Length = 5x

$\sf\pink{⟶}$ Width = 2x

But width of the ground is 40 metres.

Therefore,

$\tt:\implies{40 = 2x}$

⠀

$\tt:\implies{x = \dfrac{40}{2}}$

⠀

$\tt:\implies{x = 20}$

⠀

$\sf\pink{⟶}$ By PUTTING the value of x we will find the length of the school ground.

⠀

$\tt:\implies{Length = 5x}$

⠀

$\tt:\implies{Length = 5 \times 20}$

⠀

$\tt:\implies{Length = 100m}$

Find the integral pf sin 3x

Answer»

$\implies \displaystyle \int \sf <klux>SIN</klux> \: 3x \: dx$

$\sf \: let \: 3x = t \\ \therefore \sf3dx = dt \\ \sf dx = \dfrac{dt}{3}$

$\implies \displaystyle \int \sf sin \: t \: \frac{dt}{3}$

$\implies \displaystyle \int \sf sin \: t \: \times \frac{1}{3} dt$

$\implies \sf\dfrac{1}{3} \displaystyle \int \sf sin \: t \: dt$
