Answer:
The resultant of two forces of 7N and 3N acting at a right angle to one another is √58 N.
Step-by-step explanation:
Let the magnitude of the force of 7N be denoted as “F₁” on the x-axis and the magnitude of the force of 3N be denoted as “F₂” on the y-axis.
We are given that the two forces make an angle of 90° to one another as shown in the figure attached below.
Also, in the figure, we can see that the resultant force is denoted as “F”.
Now,
The magnitude of the resultant force can be calculated by using the Pythagoras theorem,
∴ F = √[F₁² + F₂²]
⇒ F = √[7² + 3²]
⇒ F = √[49 + 9]
⇒ F = √[58] N

Step-by-step explanation:
Since we have given that
Area of two similar decagons are 625 ft² and 100 ft² ,
As we know the relation of area of similar figures, i.e.

Now, we also know that ,

Hence,

Answer:
x=7
Step-by-step explanation:
Subtract 3x by 5x and get 2x. Then add 9 to 5 and get 14, then divide 14 by 2 and get x=7
