Let\u2019s assign variables: let the smaller angle be xx, then the larger angle is 3x+83x + 8.<\/p>\n\n\n\n<p>We are also told the angles are reflex. A reflex angle is any angle greater than 180\u00b0 and less than 360\u00b0. Initially, we try assuming <strong>both angles are reflex<\/strong>, but doing so leads to contradictory conditions. For example, if both xx and 3x+83x + 8 must be greater than 180\u00b0, then solving the inequalities leads to a result that suggests x&gt;180x &gt; 180 and x&lt;117.33x &lt; 117.33 at the same time, which is impossible.<\/p>\n\n\n\n<p>We then try reversing the variable assignment, making the larger angle xx, and the smaller one x\u221283\\frac{x &#8211; 8}{3}. But solving this again leads to contradictions, such as requiring x&gt;548x &gt; 548, which exceeds the maximum limit for an angle (360\u00b0).<\/p>\n\n\n\n<p>This tells us our assumption that <strong>both angles are reflex<\/strong> must be incorrect. Instead, we test values where only one of the angles is reflex. Trying x=88\u00b0x = 88\u00b0, the other angle becomes 3\u00d788+8=272\u00b03\u00d788 + 8 = 272\u00b0, which is a valid reflex angle.<\/p>\n\n\n\n<p>Thus, the correct and consistent solution is that one angle is 88\u00b0, and the other is 272\u00b0, satisfying both the algebraic condition and the reflex angle definition. Only the 272\u00b0 angle is reflex.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>One angle is eight more than three times another angle.
