Mathematics
1 answer:
kogti [31]2 years ago
4 0

Answer:

the value of X is 122

Step-by-step explanation:

First, all triangle angles add up to 180 so to find the missing angle we subtract  51 and 71 from 180 and get 58

Now we know straight lines always equal 180 as well so we subtract 58 from 180 and get 122 and that is the value of x

If the length of a rectangular garden is 2 feet less than the length of a house and the width of the garden is 5 feet less than
Goshia [24]

Answer:

A(h)  =  h²/2 - 6*h + 10

Step-by-step explanation:

The garden is rectangular, and area of a rectangle is:

A(r) = L*w

Where L is the length and w is the width of the rectangle

Now if we call "h" the length of the house, we have the following expressions

L = h - 2  and

w = h/2 - 5

The expression for the area f the ectangle as a function of the length of the house is:

A(h)  =  ( h - 2 )* ( h/2 -5 )

A(h)  = h²/2 - 5*h - h + 10

A(h)  =  h²/2 - 6*h + 10
