The measure of the angle of depression from the top of a 270 m building tweet park bench on the ground is 63° 43’.How far Where

Norma-Jean [14]

Answer:

547 m

Step-by-step explanation:

Given :

Angle of depression, θ = 63°43' ; 43/60 = 0.7167 = 63 + 0.7167 = 63.7167°

The height, h = 270

The distance of park bench from the building, d is given by :

Tan θ = opposite / Adjacent

Tan 63.7167 = d / 270

d = 270 * Tan 63.7167

d = 546.70459

d, distance of Park bench from building is 547 m

Eliminating by multiplying <br> X+3y=1<br> -5x+4y=-24

gavmur [86]

Answer:

y = -1 x = 4

Step-by-step explanation:

(X+3y=1) 5 Multiply this equation by 5 to cancel out the x

-5x+4y=-24

-5x + 4y= -24

+ 5x + 15y = 5 Add both equations together

19y = -19 Divide both sides by 19

y = -1

Plug -1 for y into one of the equations

x + 3(-1) = 1 Multiply 3(-1)

x - 3 = 1

+ 3 + 3 Add 3 to both sides

x = 4

Quadratic equation please help

Andre45 [30]

Answer:

x= -3+√2 or x= -3-√2 ( answer : A and B )

Step-by-step explanation:

hello :

x²+6x+9 = (x+3)².....identity

x²+6x+9 =2 means : (x+3)²=2

so : (x+3 = √2) or (x+3 = - √2)

so two solutions :

x= -3+√2 or x= -3-√2
