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
since its isosceles its a 45,45,90 right triangle which means the sides are in the proportion of x,x,x root 2
since the leg is 7 root 3 that means the hypotenuse is 7 root 6
I literally need this too and i have no idea
Answer:
Step-by-step explanation:
Because of order of operations, you do exponent first. 
. Lastly 8 multiplied by 5 is 40, so the answer is
