Respuesta :
45 degrees. Since a supplementary angle totals to 180, and a complementary totals to 90, the answer would be 45, as 45 is the compliment to 45, and 135 is the supplemnt. 135/3 is 45, so the original angle must be 45.
Answer:
45⁰
Step-by-step explanation:
Angke = x
Supplement = 180 - x
Complement = 90 - x
Given:
180 - x = 3(90 - x)
180 - x = 270 - 3x
2x = 90
x = 45⁰
