Answer:
The value of Tan (a + b) is .
Step-by-step explanation:
Given as :
Tan b =
Sin a =
∵Sin Ф =
So, =
Now, Base² = Hypotenuse² - Perpendicular²
Or, Base² = 13² - 12²
Or, Base² = 169 - 144
Or, Base² = 25
∴ Base = = 5
And Tan Ф =
Or, Tan a =
Now, Tan (a + b) =
Or, Tan (a + b) =
or, Tan (a + b) =
or, Tan (a + b) =
Or, Tan (a + b) =
Hence The value of Tan (a + b) is . Answer
The equation of the line will be y = -3.9, and the height after rounding off will be -4.
<h3>What is a straight line?</h3>
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
The horizontal line can be defined as:
y = a
Where a is the constant.
Here a = -3.9
y = -3.9
The height = -3.9 ≈ -4
Thus, the equation of the line will be y = -3.9, and the height after rounding off will be -4.
