Use Euclid divison algorithm to find the h.c.f of 135

Posted by Mihir Gopalak 5 years, 4 months ago

Gaurav Seth 5 years, 4 months ago

135 and 225 Since 225 > 135, we apply the division lemma to 225 and 135 to obtain 225 = 135 × 1 + 90 Since remainder 90 ≠ 0, we apply the division lemma to 135 and 90 to obtain 135 = 90 × 1 + 45 We consider the new divisor 90 and new remainder 45, and apply the division lemma to obtain 90 = 2 × 45 + 0 Since the remainder is zero, the process stops. Since the divisor at this stage is 45, Therefore, the HCF of 135 and 225 is 45.

(2a-b)^3+(b-c)^3+8(c-a)^3

Posted by Aishwarya Pradeep 5 years, 4 months ago

CBSE > Class 09 > Mathematics

1 answers

Gaurav Seth 5 years, 4 months ago

The given equation is,

(2a - b)³ + (b - 2c)³ + 8(c - a)³

= (2a - b)³ + (b - 2c)³ + (2c - 2a)³

Let x = (2a - b) ; y = (b - 2c) ; z = (2c - 2a)

Now,

x + y+ z = (2a - b) + (b - 2c) + (2c - 2a) = 0

Since, x + y + z = 0, then,

x³ + y³ + z³ = 3xyz

⇒ (2a - b)³ + (b - 2c)³ + (2c - 2a)³ = 3(2a - b) (b - 2c) (2c - 2a)

⇒ (2a - b)³ + (b - 2c)³ + 8(c - a)³ = 6(2a - b) (b - 2c) (c - a)

Angle OAB=30°and angle OCB=57. FIND ANGLE ABC

Posted by Supriyo Satyadarshi 5 years, 4 months ago

CBSE > Class 09 > Mathematics

2 answers

Yogita Ingle 5 years, 4 months ago

Since, OC = OB (Radii of the same circle)
∴ ∠OBC = ∠OCB
⇒ ∠OBC = 57°
In △OBC, we have
∠OBC + ∠BOC + ∠OCB = 180°
57° + ∠BOC + 57° = 180°
⇒ ∠BOC = 66°
In △OAB,we have
∠OAB + ∠OBA + ∠AOB = 180° (Since, AO=OB ∴ ∠OAB = ∠OBA)
30° + 30° + ∠AOB = 180°
⇒ ∠AOB = 180° – 60°
⇒ ∠AOB = 120°
∠ABC = 180 - ∠AOB - ∠OAB
= 180- ( 120° + 30)°
= 30°
