sp2606 [1]

Answer:

x =12

Step-by-step explanation:

The two angles add to 90 degrees

4x+4 + 5x-22 = 90

Combine like terms

9x - 18 = 90

Add 18 to each side

9x -18+18 = 90+18

9x = 108

Divide each side by 9

9x/9 = 108/9

x =12

Rewrite each expression so that each term is in the form kxn, where k is a real number, x is a positive real number,

MaRussiya [10]

Answer:

So the equation in standard form will be $x^{\frac{-1}{3}}$

Step-by-step explanation:

We have given equation $x^{\frac{-2}{3}}\times x^{\frac{1}{3}}$

We have to write this expression in standard form

For writing in standard form first we have to do operation on the expression

We know that there is property of exponent that when two functions are multiplied with each other then there exponent are added

So $x^{\frac{-2}{3}}\times x^{\frac{1}{3}}=x^{\frac{-2}{3}+\frac{1}{3}}=x^{\frac{-1}{3}}$

So the equation in standard form will be $x^{\frac{-1}{3}}$

If tanA+cotA=2 then find the value of cosA

aniked [119]

Answer:

cos A=

$\frac{1}{ \sqrt{2} }$

Step-by-step explanation:

We know,

cotA=

$\frac{1}{ \tan(a) }$

Substituting the value of cot A in the given equation, we get

$\tan( a) + \frac{1}{ \tan(a) } = 2$

$\frac{{ \tan }^{2} a + 1}{ \: \tan(a) } = 2$

${ \tan }^{2 \: } a \: + 1 = 2 tan \: a$

${ \tan }^{2} a - 2 \tan \: a + 1 = 0$

$( \tan \: a - 1) {}^{2 } = 0$

$\tan \: a - 1 = \sqrt{0}$

$\tan \: a = 1$

$\tan \: a \: = \tan \: 45$

$a = 45$

$\cos \: a = \cos \: 45$

$\cos \: a = \frac{1}{ \sqrt{2} }$
