2 tan² 45° + cos²30° - sin²60° |
|
Answer» Step-by-step explanation: The required value of the expression is 2. Step-by-step explanation: Consider the PROVIDED information. \mathrm{2\tan ^2(45^{\circ \:})+\cos ^2(30^{\circ \:})-\sin ^2(60^{\circ \:})}2tan 2 (45 ∘ )+cos 2 (30 ∘ )−sin 2 (60 ∘ ) Substitute \tan (45^{\circ \:})=1, \cos (30^{\circ \:})=\FRAC{\sqrt{3}}{2}, \sin (60^{\circ \:})=\frac{\sqrt{3}}{2}tan(45 ∘ )=1,cos(30 ∘ )= 2 3
,sin(60 ∘ )= 2 3
in above expression. \mathrm{2\tan ^2(45^{\circ \:})+\cos ^2(30^{\circ \:})-\sin ^2(60^{\circ \:})}=2\cdot \:1^2+(\frac{\sqrt{3}}{2})^2-(\frac{\sqrt{3}}{2})^22tan 2 (45 ∘ )+cos 2 (30 ∘ )−sin 2 (60 ∘ )=2⋅1 2 +( 2 3
) 2 −( 2 3
) 2
=2+\frac{3}{4}-\frac{3}{4}=2+ 4 3
− 4 3
=2=2 Hence, the required value of the expression is 2. Hope it's Helpful!!! |

-UZ6. The length of a tangent from a point A at distance 5 cm from the centre of the circle is!cm. Find the radius of the circle.Tivonnantain miles refredi 5 cm and 3 cm. Find the lenoth neu |
|
Answer» Answer: Let AT be the tangent DRAWN from a point A to a circle with centre O and OA=5 CM and AT=4 cm. Since tangent at a point is perpendicular to the radius through the point of contact ∴OT⊥AT ∴ from right angled △OAT, (OA)2=(OT)2+(TA)2 ⇒(5)2=(OT)2+(4)2 ⇒25−16=(OT)2 ⇒9=(OT)2 ⇒OT=3 cm ∴ radius of the circle =3 cm. |

2. After spending 80% of her money, Shreya is left with ? 100. How much money did she have inthe beginning?A man purchased a radio for 1250 and sold it for 1600. Find his gain or loss percent |
|
Answer» 1. Let SHREYA have the amount x x - 80%x = 100 20x/100 = 100 20x = 10000 x = 500 Therefore Shreya has 500 in the beginning. 2. C.P = 1250, S.P = 1600 Since S.P > C.P so there is gain. Gain% = [(S.P - C.P)/ C.P] × 100 = (1600 - 1250)/ 1250 × 100 = 350/1250 × 100 Gain% = 28% |

Q2.A rectangular garden has an area of 750 m². 110 m of fence has been used to fence the garden. Calculate the dimensions of the garden. |
|
Answer» Answer: Here is the explanation and the answer: Step-by-step explanation: length = L BREADTH = B Area of RECTANGLE = L * B = 750 m². Length of fence use to fence this GARDEN = 110 m perimeter = 2*(L + B) perimeter = 110 m --> 110/2 = 55, --> L + B = 55 --> 55 * 55 = 3025 2L * 2B = 3000 --> 3025 - 3000 = 25 m = Length 55 - 25 = 30 m = breadth Ans = Length = 25 m, Breadth = 30 m Hope this helps... Thankyou. |

The nth term of an AP is 7 – 4n. Find its common difference. |
Answer» Answer :COMMON difference , d = -4 Note :★ A.P. (Arithmetic PROGRESSION) : A SEQUENCE in which the difference between the consecutive terms are equal is said to be in A.P. ★ If a1 , a2 , A3 , . . . , an are in AP , then a2 - a1 = a3 - a2 = a4 - a3 = . . . ★ The common difference of an AP is given by ; d = a(n) - a(n-1) . ★ The nth term of an AP is given by ; a(n) = a + (n - 1)d . ★ If a , b , c are in AP , then 2b = a + c . ★ The sum of nth terms of an AP is given by ; S(n) = (n/2)×[ 2a + (n - 1)d ] . or S(n) = (n/2)×(a + L) , l is the last term . ★ The nth term of an AP can be also given by ; a(n) = S(n) - S(n-1) . Solution :
We know that , For an AP , the common difference d is given by d = a(n) - a(n-1) . Thus , → d = [7 - 4n] - [7 - 4(n - 1)] → d = 7 - 4n - 7 + 4(n - 1) → d = -4n + 4(n - 1) → d = -4n + 4n - 4 → d = -4 Hence ,Common difference , d = -4 . |

In the adjoining figure, ABC is a triangle in which side BC has been produced to D. If angle BAC =x°,angle ABC=(4a)°, angle BCA=a° and angle ACD=(5a)°, find the value of a and x. |
|
Answer» In the given figure, By LINEAR Pair of angles, 5A° + a° = 180° ⇒ 6a° = 180° ⇒ a = 180 ÷ 6 ∴ a = 30°In ΔABC, By Angle Sum Property, x° + 4a° + a° = 180° ⇒ x + 5a = 180° ⇒ x + 5(30) = 180° ⇒ x + 150° = 180° ⇒ x = 180° - 150° ∴ x = 30°Confused? Let's Verify !!By Angle Sum Property, x + 4a + a = 180° → x + 5a = 180° → 30 + 5(30) = 180° → 30 + 150 =180° → 180° = 180° LHS = RHS ★ Hence Verified ★ Know more:
