2 triangles measure 55 and 20 what is the measure of the third angle
2 answers:
Answer:
x = 105
Step-by-step explanation:
The angles of a triangle add to 180 degrees
Let x be the third angle
55+20 +x =180
75 +x = 180
x = 180-75
x = 105
Answer:
third triangle=105 degrees
Step-by-step explanation:
Three angles of a triangle always add up to 180. Therefore the equation is 55+20+x=180. Solving for x we get x= 105
