Rationalize the denominator !!!

satela [25.4K]

Answer:

$\frac{1\cdot \left(4+\sqrt{3}\right)}{\left(4-\sqrt{3}\right)\left(4+\sqrt{3}\right)}\\$

$1\cdot \left(4+\sqrt{3}\right)=4+\sqrt{3}$

$\left(4-\sqrt{3}\right)\left(4+\sqrt{3}\right) = 13$

$= \frac{4+\sqrt{3}}{13}$

x = 4

y = 3

z = 13

10,000 x .10 = $1000
22500-10000=12500 x .12 = $1500

Please answer ASAP. The question is down below.

zheka24 [161]

Answer: 1) c 2) a 3) d

Step-by-step explanation:

$\cos \theta = \dfrac{adjacent}{hypotenuse}\quad \\\\\\\cos 42.1=\dfrac{4.7}{x}\\\\\\x=\dfrac{4.7}{\cos 42.1}\\\\\\\large\boxed{x=6.33}\\$

******************************************************************************************

Reference angle is the angle measurement from the x-axis. There is no such thing as a negative reference angle.

-183° is 3° from the x-axis so the reference angle is $\large\boxed{3^o}$

*******************************************************************************************

Coterminal means the same angle location after one or more rotations either clockwise or counter-clockwise.

To find these angles, add or subtract 360° from the given angle to find one rotation, add or subtract 2(360°) from the given angle to find two rotations, etc.

To find ALL of the coterminals, add or subtract 360° as many times as the number of rotations. Rotations can only be integers. In other words, you can only have ± 1, 2, 3, ... rotations. You cannot have a fraction of a rotation.

Given: 203°

Coterminal angles: 203° ± k360°, k ∈ I

a triangle has one angle that measures 32 degrees and one angle that measures 102degrees. the measure of the triangle's thrid an

shutvik [7]

Step-by-step explanation:

all angles must add to 180

32+102= 134

180-134= 46

correct me if im wrong:)
