Answer:

38 degrees.

Step-by-step explanation:

There are 180 degrees in a triangle, so

m<1 = 180 - (43 + 74)

= 180 - 117

= 63 degrees.

m < 2 = m < 1 ( opposite angles) so

m < 2 = 63 degrees.

Finally, m < 3 = 180 - (63 + 79)

== 180 - 142

= 38 degrees.

Answer:

38 degrees

Step-by-step explanation:

assuming angles 1 and 2 are the same, you can get 1 by adding 74 and 43 to get 117 and 180-117 is 63. then do 63+79 to get 142. 142+38=180

Find Z for the following sequence:<br> 210, 209, 213, 186, 202, Z

nikklg [1K]

Answer:

Step-by-step explanation:

as far as I can tell the steps between the given numbers are

-1

-27

+16

1 can be expressed as 1³

4 can be expressed as 2²

27 can be expressed as 3³

16 can be expressed as 4²

my best guess is that next one is minus 5³ = -125

edit: technically the given steps can be expressed as

(-1)³

(-2)²

(-3)³

(-4)²

somewhat nicer pattern there
