Work out the equation of the line which passes through the point (-1, 2)

Brums [2.3K]

Answer:

y = x +3

Step-by-step explanation:

The equation of a parallel line can use the same x- and y-coefficients as the given equation. Only the constant needs to be found to make the line go through the given point.

<h3>form of the solution</h3>

The equation of the given line is ...

y = x +4

So, the equation of a parallel line will be ...

y = x +b . . . . . for some y-intercept b

<h3>solution</h3>

Using the given point (x, y) = (-1, 2), we can fill in the values and solve for b.

2 = -1 +b

3 = b . . . . . . add 1 to both sides

The desired equation is ...

y = x +3

Find the length of the unknown side

wel

If leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)

Determine the value of x. Round answer to the nearest hundredth. thank you to whoever helps! Will Be Marked as BRAINLIEST!

Finger [1]

Answer:

Step-by-step explanation:

Find the diagram attached

From the diagram;

Hypotenuse = 81.9

Angle of elevation = 65degrees

Required

The value of x (Adjacent)

Using the SOH CAH TOA identity

cos theta = adjacent/Hypotenuse

cos 65 = x/81.9

x = 81.9cos65

x = 81.9(0.4226)

x = 34.61

Hence the value of x to the nearest hundredth is 34.61
