A crew is painting the stripes for a new parking lot. Each of the lines that show the side of a parking space is parallel to the

next line. The measure of ∠2 is 80°. Which statement is true? Check all that apply.
Drawing of a parking lot. A vertical line is intersected by several parallel diagonal lines to form parking spaces. The angles formed by the vertical line and the first diagonal, and located above the first diagonal, are labeled 1 and 2. The angles below are labeled 3 and 4. The angles above the second diagonal are labeled 5 and 6. The angles below are labeled 7 and 8.

(A) m∠1 = 100° because ∠1 and ∠2 are corresponding angles.


(B) m∠3 = 100° because ∠2 and ∠3 are vertical angles.


(C) m∠4 = 100° because ∠2 and ∠4 are supplementary angles.


(D) m∠5 = 100° because ∠1 and ∠2 are supplementary angles and ∠1 and ∠5 are corresponding angles.

Answer:

Dibujo de un estacionamiento. Una linea vertical esta cruzada por varias lineas diagonales paralelas para formar espacios de estacionamiento. Los angulos formados por la linea vertical y la primera diagonal, y ubicados sobre la primera diagonal, estan etiquetados como 1 y 2. Los angulos de abajo estan etiquetados como 3 y 4. Los angulos por encima de la segunda diagonal estan etiquetados como 5 y 6. Los angulos de abajo son etiquetados 7 y 8.

(A) m∠1 = 100 ° porque ∠1 y ∠2 son ángulos correspondientes.

The length of a rectangle is (x + 1) cm and its width is 5cm less than its length.
NeX [460]

Answer:

a) the area of a square is in terms of x is

(x+1)^2 centimeter square

b)The length of the rectangle is l = (x+1)

                                       l = 7+1 =8 cm

The width of the rectangle is w = [(x+1)-5]

                                     w = (7+1)-5 =3 cm

Step-by-step explanation:

a) the area of a square is in terms of x is

 area of square is l^{2} = (x+1)(x+1)

                                 = (x+1)^2

b)  Given length is  l = (x+1) cm and

the width is 5 cm less than its length.

so we have take width is w = (x+1)-5 cm

Given area of triangle is  24 cm

Area of rectangle = length X width

24  =  (x+1)(x+1 -5 )

now simplification 24 = (x+1)^2 - 5 (x+1)

apply (a+b)^2 = a^2+2 a b+b^2

x^2+2 x+1-5 x-5 =24

x^2 -3 x -4-24=0

x^{2} -3 x -28 =0

now find factors of 28  = 7 X 4 is  

x^{2} -7 x+4 x-28=0

x(x-7)+4(x-7)=0

(x+4)(x-7)=0

x = -4 and x=7

there fore you have to choose x = 7

The length of the rectangle is l = (x+1)

                                       l = 7+1 =8

The width of the rectangle is w = [(x+1)-5]

                                     w = (7+1)-5 = 3

<u>Verification:-</u>

Given area of rectangle  = 24 = 8 X 3

                                           24 =24

so we can not choose x=-4

we have to choose x =7 only

A band expects to put 12 songs on their next CD. The band writes and records 25​% more songs than they expect to put on the CD.
sweet-ann [11.9K]
12 songs. 25% of 12 is 3, so you add 3 to 12 and get 15. You then find that 20% of 15 is 3 so you subtract 3 from 15 and get 12 again.

Describe how to use a tens fact to find the difference for 15-8
scoundrel [369]
Because you need to subtract from 10, you need to do 10-8. Then you will add 5 since you took away 5 to subtract from 10.
