In a right triangle, the side opposite a 33 degree angle is 17 units. What is the length of the side adjacent to that angle to t

AnnyKZ [126]

Answer:

The length of the side adjacent to that angle is 26 units

Step-by-step explanation:

We are given

In a right triangle, the side opposite a 33 degree angle is 17 units

Firstly, we will draw diagram

we can use trig

$cot(33)=\frac{x}{17}$

now, we can solve for x

$x=17\times cot(33)$

$x=26.177$

So,

The length of the side adjacent to that angle is 26 units

Calculate 7x +5 - 3x - 7 = 10

vredina [299]

You answer is 3 and here's why...

7x + 5 - 3x - 7 = 10

First you must collect like terms

And that gives us

4x - 2 = 10

Next you must simplify by removing additives

4x - 2 + 2 = 10 + 2

4x = 12

Now you must divide

4x/4 = 12/4

x = 3

Answer:

$\displaystyle 1\frac{1}{3}$

Step-by-step explanation:

[3, 1] and [0, −3]

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{3 + 1}{0 + 3} = \frac{4}{3} = 1\frac{1}{3}$
