The required value of is m∠2 = 18°.
Given that,
First complementary adjacent angel m∠1 = 72°
We have to find,
Second complementary adjacent angle m∠2.
According to the question,
In geometry, the two angles are said to be complementary angles if they add up to 90 degrees.
Such as, m∠1 + m∠2 = 90°.
Where, m∠1 = 72°
Putting the value of m∠1 = 72° in the equation,
72° + m∠2 = 90°
m∠2 = 90° - 72°
m∠2 = 18°
Hence, The required value of is m∠2 = 18°.
