Question

Pls anyone could help me with this?

Answer 1

180-51-25=104 to find the third angle, you subtract the other ones with 180 since there are 180 degrees in a triangle

180-104-34=42

missing angle = 42

the other two blank angles besides the missing ones are congruent, that’s why i typed 180-104-34

Answer 2

Answer: 42 degrees

Step-by-step explanation:

Alright so we have 51 and 25 in the first triangle that would mean we have to subtract 180 by 76, since every triangle has 180 degrees.

180 - 76 = 104

that means the other side is 104 and by adding 34 and using the same concept,

180 - 138 = 42!
