Alja [10]

Answer:

The base of the ladder is 2.58 m.

Step-by-step explanation:

Given that,

The angle of elevation for a ladder from the ground is 75°.

The length of a ladder, H = 10 foot

We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,

$\cos\theta=\dfrac{B}{H}\\\\B=H\times \cos\theta\\\\B=10\times \cos(75)\\\\B=2.58\ m$

So, the base of the ladder is 2.58 m.

-3x-2y=-1<br> 4x+6y=12<br><br> what’s all the steps and answer to this equation

abruzzese [7]

Answer:

x = -9/5

y = 16/5

Step-by-step explanation:

-3x-2y=-1 first you need to multiply the numerator by 3 so when adding

4x+6y=12 the y's cancel and you get a single variable

3(-3x-2y=-1) —> -9x - 6y = -3 then you add the like terms

4x+6y=12 —> 4x + 6y = 12

(-9x+4x) + (6y - 6y) = (-3 + 12)

-5x = 9 then you divide by -5

x = -9/5

then you plug this in to either equation

4(-9/5) + 6y = 12

-36/5 + 6y = 12 then you add 36/5 to both sides

6y = 96/5 then you divide by 6

y = 16/5
