Ireally need understanding this! .

find the measures of all the numbered angles in the figure below.

angle 1=

angle 2=

angle 3=

angle 4

angle 5=

angle 6=

angle 7=

Below in bold.

Step-by-step explanation:

Note that the lines q and m are parallel.

m < 1 = 180 - 110 = 70 degrees.  ( adjacent angles)

m < 2 =  180 - 115 = 65 degrees ( adjacent angles)

m < 3 = m < 2 = 65 degrees ( lines q and m are parallel and 2 and 3 are corresponding angles).

m < 4 = 180 - 65 = 115 degrees (adjacent to < 3).

m < 5 = 180 - m < 1 - m < 3 = 180 - 70 - 65 = 180 - 135 = 45 degrees. ( angles in a triangle add up to 180 degrees).

m < 6 = m < 5 = 45 degrees (  q and m are parallel - alternate angles).

m < 7 =- m < 6 = 45 degrees ( opposite angles).

(4, -0.6)

Step-by-step explanation:

The missing options are:

(1, -1.6)  

(2, 1.5)  

(3, 4.5)

(4, -0.6)

From the first and fourth columns of the table:

x    residual

1     -0.4

2    0.7

3    -0.2

4    -0.6

Therefore, the points of the residual plot are: (1, -0.4), (2, 0.7), (3, -0.2) and (4, -0.6)
