Answer:
45°
Step-by-step explanation:
<u>Let </u><u>:</u><u>-</u><u> </u>
<u>We </u><u>know </u><u>:</u><u>-</u>
The sum of supplementary angles is 180° .
<u>On </u><u>adding</u><u> </u><u>:</u><u>-</u><u> </u>
→ x + 3x = 180°
→ 4x = 180°
→ x = 180°/4
→ x = 4 5 °
<h3>
Hence the smaller angle is 4 5 ° . </h3>
