Answer:

(first and brainliest??) 27 degrees

Step-by-step explanation:

The top triangle's missing angle is 75 degrees because 85+20=105 and 180-105=75. Knowing this, we know that the angle that's connecting the two triangles is also 75 degrees. 78+75=153 and 180-153=27

Answer:

27 degrees.

Step-by-step explanation:

20 + 85 + n = 180

105 + n = 180

180 - 105 = 75

Check: 75 + 85 + 20 = 180

180 = 180

75 + 78 + n = 180

153 + n = 180

180 - 153 = 27

Check: 75 + 78 + 27 = 180

180 = 180

If the triangle are similar, write a similarity

Vesna [10]

Answer:

The triangles are similar due to AAA

Step-by-step explanation:

'The triangles ABC and DBE are similar because they have a common angle < B, and also angle < E is marked as congruent to angle < A. Then the third angle <C is going to be congruent to angle D as well due to the property of addition of internal angles of a triangle must add to 180 degrees.

Then the triangles are similar due to AAA
