The value of x in the given equation is 0.03
<u>Step-by-step explanation:</u>
The given equation is that
<u>The steps to be followed to solve the equation are :</u>
Add the like terms together to reduce the equation in a simplified form.
Here, there are two x terms and they must be reduced to a single term.
For this, add the both terms together so that the equation is simplified into one x term and a constant term.
⇒
⇒
To eliminate the constant term on the left side of the equation, add 0.1245 on both sides.
⇒
⇒
Now, the equation is further simplified by dividing 4.15 on both sides,
⇒
⇒
Therefore, the value of x is 0.03
Answer:
1.84
Step-by-step explanation:
The given arc is a part of a unit circle centered at origin.
The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.
So, for angle equal to °, the x coordinate represents
°.
So, ° = 0.86
Similarly, the y-coordinate of angle y represent °.
So, ° = 0.98
Therefore, the value of ° +
° = 0.86 + 0.98 = 1.84.
