Answer:

x = 11√3

y = 22

Step-by-step explanation:

In a 30-60-90 triangle, the hypotenuse is twice the shortest side.

y = 22

The long side is √3 times the short side.

x = 11√3

If you wish to use trigonometric functions:

sin 30° = 11 / y

1/2 = 11 / y

y = 22

tan 30° = 11 / x

1 / √3 = 11 / x

x = 11√3

Help please? 10 points. Correctly

Romashka [77]

From the Figure :

Point A is (-3 , -3)

Point B is (6 , 6)

We know that, The Mid Point of Two Points (x₁ , y₁) and (x₂ , y₂) is given by :

$\mathsf{\implies [(\frac{x_1 + x_2}{2})\;,\;(\frac{y_1 + y_2}{2})]}$

$\mathsf{\implies Midpoint\;of\;Line\;AB\;is\;[(\frac{-3 + 6}{2})\;,\;(\frac{-3 + 6}{2})]}$

$\mathsf{\implies Midpoint\;of\;Line\;AB\;is\;[(\frac{3}{2})\;,\;(\frac{3}{2})]}$

$\mathsf{\implies Midpoint\;of\;Line\;AB\;is\;(1.5,1.5)}$

It’s due tomorrow plz HELP

$\dfrac{3}{4} + 5 - \dfrac{1}{2} = \dfrac{3}{4} + \dfrac{20}{4} - \dfrac{2}{4} = \dfrac{21}{4} = 5 \dfrac{1}{4}$

$\dfrac{2}{3} + {2}^{3} - \dfrac{1}{3} = \dfrac{2}{3} + \dfrac{24}{3} - \dfrac{1}{3} = \dfrac{25}{3} = 8 \dfrac{1}{3}$

$- 15 + 6x - 19 - 20x = - 14x - 34$

$- 7x - 2 - 9y + 10x = 3x - 9y - 2$

$14 + x = 18 \\ x = 18 - 14 \\ x = 4$

$- 5x = - 15 \\ x = - 15 \div ( - 5) \\ x = 3$

$- 2x + 8 = 18 \\ - 2x = 18 - 8 \\ - 2x = 10 \\ x = 10 \div ( - 2) \\ x = - 5$

$3x + 18 - 8x = - 17 \\ 3x - 8x = - 17 - 18 \\ - 5x = - 35 \\ x = - 35 \div ( - 5) \\ x = 7$

How do you solve this? 18 " n=21

dalvyx [7]

$18 ^{n} =21$

$log(18) ^{n}=log(21)$

$n*log(18)=log(21)$

$n= \frac{log(21)}{log(18)}$

$n=1.053$
