Hello,

n + ( 2n - 30 ) = 90

n + 2n - 30 = 90

3n - 30 = 90

3n = 30 + 90 = 120

n = 120 / 3 = 40°

Let x = other angle of two complementary angles

One of two complementary angles is 30 less than twice other: 2x - 30

Sum of complimentary angles add to be 90 degrees

x + 2x - 30 = 90

3x = 120

x = 40

Answer

40 degrees

Find the multiplicative inverse of 3 − 2i. Verify that your solution is corect by confirming that the product of
leonid [27]

Answer:

\frac{3}{13} + \frac{2i}{13}

Step-by-step explanation:

The multiplicative inverse of a complex number y  is the complex number z such that (y)(z) = 1

So for this problem we need to find a number z such that

(3 - 2i) ( z ) = 1

If we take z = \frac{1}{3-2i}

We have that

(3- 2i)\frac{1}{3-2i} = 1 would be the multiplicative inverse of 3 - 2i

But remember that 2i = √-2 so we can rationalize the denominator of this complex number

\frac{1}{3-2i } (\frac{3+2i}{3+2i } )=\frac{3+2i}{9-(4i^{2} )} =\frac{3+2i}{9-4(-1)} =\frac{3+2i}{13}

Thus, the multiplicative inverse would be \frac{3}{13} + \frac{2i}{13}

The problem asks us to verify this by multiplying both numbers to see that the answer is 1:

Let's multiplicate this number by 3 - 2i to confirm:

(3-2i)(\frac{3+2i}{13}) = \frac{9-4i^{2} }{13}  =\frac{9-4(-1)}{13}= \frac{9+4}{13} = \frac{13}{13}= 1

Thus, the number we found is indeed the multiplicative inverse of  3 - 2i

Answer:

B

Step-by-step explanation:

Let’s name the side opposite to ∏/3 = X

Let’s name the side opposite to ∏/6 = Y

tan ∏/3 = √3 = X/Y

Then , X = √3 x Y
