Answer:
y=10.4
Step-by-step explanation:
If you mean Y instead of x then the answer is 10.4
3.8+y=14.2
-3.8 -3.8
y=10.4
Answer:
114.96 pounds at angle 81.76°
Step-by-step explanation:
Let i be the component along x-axis and j be the component along y-axis.
First force that is given is 150 acting at angle 40; ![F1 = 150cos170i + 150sin40j = 114.91i +96.42j](https://tex.z-dn.net/?f=F1%20%3D%20150cos170i%20%2B%20150sin40j%20%3D%20114.91i%20%2B96.42j)
The second force 100 is acting at angle 170;
![F2 = 100cos170i + 100sin170j = -98.48i + 17.36j](https://tex.z-dn.net/?f=F2%20%3D%20100cos170i%20%2B%20100sin170j%20%3D%20-98.48i%20%2B%2017.36j)
We now have the resultant force, which is: ![114.91i + 96.42j + (-98.48i + 17.36j) = 16.43i + 113.78j](https://tex.z-dn.net/?f=114.91i%20%2B%2096.42j%20%2B%20%28-98.48i%20%2B%2017.36j%29%20%3D%2016.43i%20%2B%20113.78j)
Magnitude of resultant:
= 114.96 pounds
Angle it makes with horizontal; inverse tangent of
= 81.76 degrees
Hope this helps; Brainliest appreciated!
Answer:
it's d
Step-by-step explanation:
shaded circle means that number and up or down
ansd unshaded means up or down.
-3 is shaded so it includes -3 and below
while 1 isnt so it has to be below 1
The answer is actually A. Sides are named by their angles.
Answer:
= is your answer
Step-by-step explanation:
Note the name of the symbols.
"<" means <em>less than</em>
">" means <em>greater than</em>
"=" means <em>equal</em>
"≤" means <em>less than or equal to</em>
"≥" means <em>greater than or equal to</em>
When x equals 3, it means x = 3
