Answer:
121 – 1 = 120. 120 – 3 = 117.
Step-by-step explanation:
Answer: 25° and 65°
Step-by-step explanation:
Let the smaller angle of the complementary angle be represented by x.
Since the other angle is 15 degree more than two times the other angle, this will be:
= (2 × x) + 15°
= 2x + 15°.
Then we add both angles together and equate them to 90° and this will be:
x + 2x + 15° = 90°
3x + 15° = 90°
3x = 90° - 15°
3x = 75°
x = 75°/3
x = 25°
Then the other angle will be:
= 2x + 15°
= (2 × 25°) + 15°
= 50° + 15°
= 65°
Therefore, the angles are 25° and 65°.
