Answer:
-1, 0
Step-by-step explanation:
i think <33
Answer: 56 degrees
Step by step:
The three angles in a triangle add up to 180 degrees.
49 + 75 + the third angle = 180
Let’s simplify.
180 - 49 - 75 = the third angle
So, by subtracting, we know that the third angle is 56 degrees!
Hope this helps! Please tell me if I did anything wrong, thank you so much and have a good day!
Perimeter of the triangle, a+b+c
In this case, a=b=c=28
So, perimeter would be 28*3 = 84 cm
