Two angles of a quadrilateral are 65° and 120°. If the other two angles are equal, find the measure of each of the equal angles.

Answer»

Hey MATES!!

we know that SUM of all SIDE of quad is 360

Than,

let a and b be = X

a+ b+ c+ d = 360

a+ b+ 65° + 120° = 360

a+ b + 185 = 360

a+ b = 360 - 185

a+ b = 175

35.

If x2 -5x+1 = 0 , then x3 + 1/x3 is equal to ???

Answer»

Answer:

110

Step-by-step explanation:

Given:

x² - 5x + 1 = 0

To FIND:

The value of

${x}^{3} + \dfrac{1}{ {x}^{3} }$

Solution:

${x}^{2} - 5x + 1 = 0 \\ \\ {x}^{2} + 1 = 5x$

[Dividing both side by x ]

$x + \dfrac{1}{x} = \: 5 \: \: ---(1)$

[Now, cubing both side ]

${(x + \frac{1}{x} )}^{3} = {5}^{3} \\ \\ {x}^{3} + \frac{1}{ {x}^{3} } + 3.x. \frac{1}{x}( x + \frac{1}{x} ) = 125 \\ \\ {x}^{3} + \frac{1}{ {x}^{3} } + 3. \cancel{x}. \frac{1}{\cancel{x}} ( x + \frac{1}{x} ) = 125 \\ \\$ ${x}^{3} + \frac{1}{ {x}^{3} } + 3(5) = 125 \:\:\: [\text{From 1}] \\ \\ {x}^{3} + \frac{1}{ {x}^{3} } = 125 - 15 \\ \\ {x}^{3} + \frac{1}{ {x}^{3} } = 110$

THEREFORE, the REQUIRED answer is 110.
