3.

At a charity benefit with 22 people in attendance, three $50 gift certificates are given away as door prizes. Assuming no person receives more than one prize, in how many different ways can the gift certificates be awarded?

Answer»

$\huge{\underline{\mathtt{\red {A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

In the Isosceles TRIANGLE ABC,

∠BAC = 30°

So,

∠CBA also = 30° = X (Opposite side in a Isosceles ∆)

_____________________________________

If ∠BAC & ∠CBA = 30°

Then,

∠BAC + ∠CBA + ∠ACB = 180° (Angle Sum Prop. of a Triangle)

➠ 30° + 30° + ∠ACB = 180°

➠ ∠ACB = 180° - 60°

➠ ∠ACB = 120°

If ACB = 120° Then,

∠BCD = 180° - 120°

∠BCD = z = 60°

___________________________________

If z = 60°

Then,

Y also = 60° (OPP. Sides in an Isosceles ∆ )

____________________________________

OVERALL,

x = 30°

y = 60°

z = 60°

Step-by-step explanation:

The perimeter of a rectangle has the formula : 2 ( L + B )

Perimeter = 2 ( L + B )

100 cm = 2 ( 35 + B )

100 cm = 70 + 2B

100 - 70 = 2B

30 = 2B

15 = B

breadth = 15 cm

The formula for a rectangle's area is ( L X B )

area of the rectangle = L x B

= 35 x 15

= 525 cm²

Hope this HELPED.

Answer» Answer:- GIVEN: Cosec θ + cot θ = k -- equation (1) we know that, cosec² θ - cot² θ = 1 a² - b² = (a + B)(a - b) So, ⟶ (cosec θ + cot θ) (cosec θ - cot θ) = 1 ⟶ k * (cosec θ - cot θ) = 1 [ From equation (1) ] ⟶ Cosec θ - cot θ = 1/k -- equation (2) Add equations (1) and (2) $\longrightarrow \sf \: \csc \theta + \cot \theta + \csc \theta - \cot \theta = k + \frac{1}{k} \\ \\ \\\longrightarrow \sf \: 2 \csc \theta = \frac{ {k}^{2} + 1 }{k} \\ \\ \\ \longrightarrow \sf\csc \theta = \frac{ {k}^{2} + 1 }{k} \times \frac{1}{2} \\ \\ \\ \longrightarrow \boxed{\sf\csc \theta = \frac{ {k}^{2} + 1 }{2k} }$ cot θ = Cosec θ * COS θ So substitute the value of cosec θ in equation (1). ⟶ Cosec θ + cosec θ * cos θ = k ⟶ cosec θ (1 + cos θ) = k $\: \longrightarrow \sf \: \frac{ {k}^{2} + 1 }{2k} \bigg(1 + \cos \theta \bigg) = k \\ \\ \\ \longrightarrow \sf \:1 + \cos \theta =k \times \frac{2k}{ {k}^{2} + 1} \\ \\\\ \longrightarrow \sf \: \cos \theta = \frac{2 {k}^{2} }{ {k}^{2} + 1 } - 1 \\ \\\\ \longrightarrow \sf \:\cos \theta = \frac{2 {k}^{2} - ( {k}^{2} + 1)}{ {k}^{2} + 1} \\\\ \\ \longrightarrow \sf \:\cos \theta = \frac{2 {k}^{2} - {k}^{2} - 1}{ {k}^{2} + 1} \\\\ \\ \longrightarrow \boxed{\sf \:\cos \theta = \frac{{k}^{2} - 1}{ {k}^{2} + 1}}$ Hence Proved.

If cosec titar+ cot titar=K then prove that cos titar=ke power 2 -1 bye ke power 2 +1

Answer»

Answer:-

GIVEN:

Cosec θ + cot θ = k -- equation (1)

we know that,

cosec² θ - cot² θ = 1

a² - b² = (a + B)(a - b)

So,

⟶ (cosec θ + cot θ) (cosec θ - cot θ) = 1

⟶ k * (cosec θ - cot θ) = 1

[ From equation (1) ]

⟶ Cosec θ - cot θ = 1/k -- equation (2)

Add equations (1) and (2)

$\longrightarrow \sf \: \csc \theta + \cot \theta + \csc \theta - \cot \theta = k + \frac{1}{k} \\ \\ \\\longrightarrow \sf \: 2 \csc \theta = \frac{ {k}^{2} + 1 }{k} \\ \\ \\ \longrightarrow \sf\csc \theta = \frac{ {k}^{2} + 1 }{k} \times \frac{1}{2} \\ \\ \\ \longrightarrow \boxed{\sf\csc \theta = \frac{ {k}^{2} + 1 }{2k} }$

cot θ = Cosec θ * COS θ

So substitute the value of cosec θ in equation (1).

⟶ Cosec θ + cosec θ * cos θ = k

⟶ cosec θ (1 + cos θ) = k

$\: \longrightarrow \sf \: \frac{ {k}^{2} + 1 }{2k} \bigg(1 + \cos \theta \bigg) = k \\ \\ \\ \longrightarrow \sf \:1 + \cos \theta =k \times \frac{2k}{ {k}^{2} + 1} \\ \\\\ \longrightarrow \sf \: \cos \theta = \frac{2 {k}^{2} }{ {k}^{2} + 1 } - 1 \\ \\\\ \longrightarrow \sf \:\cos \theta = \frac{2 {k}^{2} - ( {k}^{2} + 1)}{ {k}^{2} + 1} \\\\ \\ \longrightarrow \sf \:\cos \theta = \frac{2 {k}^{2} - {k}^{2} - 1}{ {k}^{2} + 1} \\\\ \\ \longrightarrow \boxed{\sf \:\cos \theta = \frac{{k}^{2} - 1}{ {k}^{2} + 1}}$

Hence Proved.
