Question

Manasa says, “Each angle in any pair of complementary angles is always acute”. Do you agree? Give reason.
sol: complementary angles are those angles whose sum is equal to 90°
Acute angles are those whose value is less than 90°
let's suppose one acute angle is m and another acute angle is n
Since we know m ≤ 90°
n ≤90°
so add the value of m and n each other m ± n ≤ 90°
this shows if m & nare acute angle then their sum can never except than 90°

​

Answer 1

Answer:

The solution is true

they can never be more than 90°

m+n=90°

m<90°

n<90°
