AB = 3x
Anvisha [2.4K]

Answer:

see explanation

Step-by-step explanation:

If a parallelogram then AB = DC and AD = BC

Equating AB = DC, then

3x = x + 4 ( subtract x from both sides )

2x = 4 ( divide both sides by 2 )

x = 2

Thus

AB = 3x = 3(2) = 6 and DC = x + 4 = 2 + 4 = 6 ⇒ AB = DC

Equating AD and BC, then

2y = y + 2 ( subtract y from both sides )

y = 2

Thus AD = y + 2 = 2 + 2 = 4 and BC = 2y = 2(2) = 4 ⇒ AD = BC

Since opposite sides are congruent then ABCD is a parallelogram

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements?
Sati [7]

Answer:

The value is  m  = 0.9022

Step-by-step explanation:

From the question we are told that

    The length of the treads is  a =  9 \  inch

     The length of the risers is  b  =  8.12 \  inch

Generally the slope of the staircase is

         m  =  \frac{b}{a}

=>       m  =  \frac{8.12}{9}

=>       m  = 0.9022
