All interior angles equal to 180 just add the two angles you have and subtract it from 180 to get the final angle

Answer:
no it can't because
Step-by-step explanation:
coz the sum of any two angle should be greater than 3rd side
- 13 + 5 = 18 which is greater than 7
- 13 + 7 = 20 which is greater than 5
- 5 + 7 = 12 which is not greater than 13
so triangle cant be made
