Answer:

=> R = ~25 deg

Step-by-step explanation:

Apply the sine theorem:

PQ/sinR = RP/sinQ

=> sinR = (PQ/RP)*sinQ

= (20/36)*sin(50 deg)

= 0.4256

=> R = ~25 deg

Hope this helps!

Rationalize the denominator<br><br> 11/Square root of 5 - square root of 6

olasank [31]

Answer:

$-11\sqrt{5}-11\sqrt{6}$

Step-by-step explanation:

The given radical expression is;

$\frac{11}{\sqrt{5}-\sqrt{6}}$

We multiply both the numerator and the denominator by the conjugate of

$\sqrt{5}-\sqrt{6}$ which is $\sqrt{5}+\sqrt{6}$

$\frac{11(\sqrt{5}+\sqrt{6})}{(\sqrt{5}-\sqrt{6})(\sqrt{5}+\sqrt{6})}$

The denominator is now difference of two squares;

$\frac{11(\sqrt{5}+\sqrt{6})}{(\sqrt{5})^2-(\sqrt{6})^2}$

Simplify:

$\frac{11(\sqrt{5}+\sqrt{6})}{5-6}$

$\frac{11(\sqrt{5}+\sqrt{6})}{-1}$

$-11(\sqrt{5}+\sqrt{6})$

$-11\sqrt{5}-11\sqrt{6}$

Decreasing 3/4 times a number by 18 is equal to increasing 1/2 times the number by 5 give an equation and solution to the situat

Maslowich

Answer:

Step-by-step explanation:

Let the number be x.

As per the question,

3/4x - 18 = 1/2x + 5

(4)3/4x - (4)18 = (4)1/2x + (4)5

3x - 72 = 2x + 20

x = 92

The number is 92.
