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
