If the sum of measures of two angles is $180 °$ and one of them is acute, then the other is a/an_____.

Open in App

Solution

Acute Angle – an angle measure less than $90 °$ .
Obtuse Angle – an angle whose measure is greater than $90 °$ and less than $180 °$ .
Hence, It must be more than $90 °$ because one of them is acute.
