A ladder is leaning against the side of a building. The

cupoosta [38]

Answer:

16 ft

Step-by-step explanation:

Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:

c = √( a² + b²)

In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.

c² = a² + b²

a² = c² - b²

a = √( c² - b² )

a = √( 20² - 12² )

a = 16

The unit is in ft.

Correct me if I'm wrong. I hope it helps.

2x+3y=0 and x+2y=-1 Solve by substitution

dmitriy555 [2]

Answer:

The solution of the given equations is (-3,2)

Step-by-step explanation:

Step:1

The Given equations are 2 x+3 y=0 .......(1)

x+2 y-1 =0.........(2)

Step 2:-

Solving both equations by using substitution method

multiply equation (2) with number '2' ,

2 x+4 y-2=0.......(3)

subtracting the equations (1) and (3) and cancelled 'x' terms

we get $3y-4y=0-2$

$y=2$

Step 3:-

substitute y= 2 in equation (1) we get

$2 x+3 y=0$

$2 x+3(2)=0$

$2 x=-6$

$x=-3$

Final answer:-

The solution of the given equations is (-3,2)
