Answer:

The measure of angle two is 47 degrees (first triangle), and the measure of angle four is 42 degrees (second angle)

Step-by-step explanation:

Remember that all triangles have a full measurement of 180 degees.

Since measure one is is 65 degrees, we need to add 65 and 68, which is 133 degrees.

Now we subtract 180 - 133 = 47.

The measure of angle two is 47 degrees.

Since the angle of measure three is 89 degrees, we need to add 89 + 49, which is 138 degrees.

180 - 138 = 42.
