1. Which of the following pairs of angles are complementary? $80^{2}$ $90^{°}$ $\sqrt{}$ $\bar{\sqrt{30^{°}} }$ $90^{°}$ $110^{°}$ $\left(1\right)$ $.$ $\left(\vec{1} 1\right)$ (111) $2.$ Find the complementary angles otf he following. $\left(1\right)$ $250$ $\left(1\vec{1} \right)$ $400$ $\left(\vec{1} \vec{1} 1\right)$ $890$ $\vec{1} \right)$ $550$ $3.$ Two angles are complement to each other and are also equal. Find them. 4. Manasa says, "Each angle in any pair of complementary angles is always acute". Do you agree? Give reason.
