-STEP explanation:Given: x+y =3. --1eq. 3x^2 + y^2 = 5 --2eq.Solution: x = 3-yputting VALUE of x in 2 eq.3(3-y)^2 + y^2 = 53(9 + y^2 + 6y) +y^2 =527 +3Y^2 + 6y +y^2 = 54y^2 +6y +27 - 5= 04y^2 +6y +22= 02(2y^2 + 3y + 11) =02y^2 + 3y + 11= 0now you can solve it by discrimination method

given :-3/6 and 3/4here we've to find any three rational numbers between them THOUGH they've ∞ rational numbers between them.so first of all, we needa make the denominators of both rational numbers sameLCM of 6 and 4 = 2 × 2 × 3= 123/6 = (3 × 2)/(6 × 2)= 6/123/4 = (3 × 3)/(4 × 3)= 9/12still we don't have enough rational numbers.let's multiply both the fractions by 2» 6/12 = (6 × 2)/(12 × 2) = 12/24» 9/12 = (9 × 2)/(12 × 2) = 18/24hence, three rational numbers between them are 13/24, 14/24 and 15/24there are many other rational numbers too.. it's up to U.. you can choose any 3.

cos theta = √7tan theta = √6 / √7Step-by-step explanation:GIVEN, SIN theta = √6We know that, Trigonometry is applied in the right triangles. Thus the given triangle is right angled triangle. And, sin theta = Perpendicular / HypotenuseAlso, sin theta = √6 = √6/1Then, We get, Perpendicular /HYPOTENUSE = √6/1So, let Perpendicular = x√6 and Hypotenuse = 1x, where x is the constant by which both 1 and √6 is MULTIPLIED. Now, applying Pythagoras theorem, we get, (Hypotenuse)^2 = (Perpendicular)^2 + (Base)^2=> (1x)^2 = (x√6)^2 + (Base)^2=> x^2 = 6x^2 + (Base)^2=> (Base)^2 = 7x^2=> Base = √7x^2 = x√7Now, Cos theta = Base/Hypotenuse = x√7 / 1x = √7 / 1 = √7Tan theta = Perpendicular/Base = x√6 / x√7 = √6 / √7

-The NUMERATOR of a rational NUMBER is 8 less than its denominator if the numerator is INCREASED by 2 and the denominator is decreased by 1 the number obtained is 1 /2 .Tᴏ ғɪɴᴅ :-Rational Number sᴏʟᴜᴛɪᴏɴ :-Let the rational number be X / ythen, According to 1st Condition :-➦ Numerator = Denominator - 8➦ x = (y - 8) . ----(1)According to 2nd Condition :-We get, ➦ 2x - y = -5 .---(2)Put the value of (1) in (2) , we get, ➮ 2x - y = -5➮ 2(y - 8) - y = -5➮ 2y - 16 - y = -5➮ y = -5 + 16➮ y = 11Put y = 11 in (1) , we get, ➮ x = y - 8➮ x = 11 - 8➮ x = 3Hence, Rational Number is x/y = 3/11

Step-by-step explanation:FIND the perimeter of an isosceles RIGHT triangle whose area is 200 cm^2.since , we know that in isosceles triangle two sides are always EQUAL. but here given that the isosceles triangle is right triangle . if the triangle is isosceles right triangle then its base and height will be equal.why hypotenuse will not be equal either to height or base of isosceles right triangle ?its because , according pythagoras theoremif the triangle is right (90°) then the LENGTH of hypotenuse of that triangle will always be greater than the base and the height of that triangle.let b be the hypotenuse and ( a , a ) be the base and height of isosceles right triangle.from ∆ ABCarea of isosceles right triangle=200cm^2( 1 / 2 ) × base × height = 200( 1 × a × a ) / 2 = 200a^2 = 400 => a = √400 => a = 20 cmnow in ∆ ABC ,by Pythagoras theorem , we get(AC)^2 = ( BC )^2 + ( AB )^2b^2 = ( 20 )^2 + ( 20 )^2b^2 = 400 + 400 = 800b = √800 => 28.2 cm ( approx. )since , we know that perimeter of triangle= sum of all the sides of triangle.therefore, perimeter of isosceles right triangle= a + a + b = 20 + 20 + 28.2 = 68.2 cmYour Answer : 68.2 cm THEREFORE, Perimeter of an isosceles right triangle whose area is 200 cm= 68.2 cm
