im soooo sorry but i dont know 44
Draw 4 squares. The perimeter is 10 because the width is 4 and the length is 1. So 4 x 2 is 8 and 1 x 2 is 2. And 8 + 2 = 10.
Answer:
4. No because 2×4=8 but 5×4 doesn't equal 18

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°
