Answer:
Step-by-step explanation:
So this is an isosceles triangle so the other angle must be x too.
So:
x+x+40 = 180
2x+40 = 180
2x = 140
x = 70
Answer:
i think 70 degrees
Step-by-step explanation:
becuase all triangles and up to 180 degrees
70+ 70(becuase two sides are equal ) and +40 equals 180 degrees.. i think 70 is the answer(not sure i'm not a pro when it comes to maths... but that my final answer.
