Answer:
B. input
Step-by-step explanation:
Answer:2:8 , 3:12, 4:16, 5:20
Step-by-step explanation:
3<em>x</em> + 120° + <em>x</em> + 120° = 360°
4<em>x</em> + 240° = 360°
4<em>x</em> = 120°
<em>x</em> = 30°
<em>y</em> = 1/2 (3<em>x</em> - <em>x</em>)
<em>y</em> = 1/2 (90° - 30°)
<em>y</em> = 1/2 × 60°
<em>y</em> = 30°
75 - 75 = 0, therefore, your answer is equal to zero
