take one of the ordered pairs and you’re going to plug it into
5=-4(x+2)
5=-4x-8
-5 -5
y=-4x-13
Answer:
The measure of angle LKJ is 49°
Step-by-step explanation:
<u><em>The correct question is</em></u>
The equation tan−1 = {8.9/7.7} x can be used to find the measure of angle LKJ. What is the measure of angle LKJ?
Round to the nearest whole degree.
see the attached figure to better understand the problem
Let
x -----> the measure of angle LKJ
we know that
![tan(x)=\frac{8.9}{7.7}](https://tex.z-dn.net/?f=tan%28x%29%3D%5Cfrac%7B8.9%7D%7B7.7%7D)
so
![x=tan^{-1}(\frac{8.9}{7.7})](https://tex.z-dn.net/?f=x%3Dtan%5E%7B-1%7D%28%5Cfrac%7B8.9%7D%7B7.7%7D%29)
using a calculator
![x=49.13\°](https://tex.z-dn.net/?f=x%3D49.13%5C%C2%B0)
Round to the nearest whole degree
![x=49\°](https://tex.z-dn.net/?f=x%3D49%5C%C2%B0)
therefore
The measure of angle LKJ is 49°
Easy,
23y-(7x-2y)+x
<span>There is an imaginary</span> 1 in front of the parentheses, making it,
23y-1(7x-2y)+x
Now, distribute the 1.
-1*7x= -7x
and
-1*-2y= 2y
Leaving your problem looking like...
23y-7x+2y+x
Combine your apples and oranges.....
25y-6x
Thus, your answer.
