Question

What is the measure of angle 3, in degrees, in the figure shown?

Answer 1

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 2

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
