Answer:
A) 30°
Step-by-step explanation:
Sum of three angles of a triangle = 180°
75° +75° + ∠WYZ = 180°
Add like terms
150° + ∠WYZ = 180°
Subtract 150°from both sides
∠WYZ = 180 - 150
∠WYZ = 30°
Answer:
0.06x + 0.15y = 69.84
x = (69.84 - 0.15y) / 0.06
y = (69.84 - 0.06x) / 0.15
x + y = 852
((69.84 - 0.15y) / 0.06) + y = 852
y = ?
(I'm not trying to give you the answer but guide you how to do it)
we will check each options
option-A:
The modulus represents the distance between the complex number and the origin
we know that modulus is a kind of distance
For example: if we have to find modulus of x+iy
we get
that is also distance between (0,0) and (x,y)
so, this is TRUE
option-B:
It is also similar to Pythagoras theorem
so, this is also TRUE
option-C:
we got modulus formula
we know that value of sqrt can never be negative because it will always result in positive value
so, this is FALSE
option-D:
It is also similar to absolute value
so, this is TRUE
I'm sorry but I don't know the answer to your question.
Please find the attachment for a better understanding of the solution provided here.
We have been asked to find the work done by a force F of 21 pounds acting in the direction <2,5> in moving an object 7 feet from (0,0) to (7,0).
As we can see clearly from the question above that the object moves exclusively in the direction of the x axis and thus, the component of the force acting is only the x component. So, our main aim will be to find the x component of the force. Once it is found we will simply multiply it with the distance travelled in the x axis to find the work done as asked in the question.
Let us call the x component of the force as .
From the diagram in the attachment, we can see that the degrees
Thus, feet
feet-pound
Thus, A is the correct option
