Define Acute Angle

Define acute and chronic disease.

If If and and are acute angles such that are acute angles such that then show that /_A=/_B

Angle of 0^(@) is an acute angle.

A triangle must have ( 1) Exactly two acute angles (2) At least two acute angles (3) Exactly three acute angles (4) At most one acute angle

Acute angle an angle whose measure is greater than 0^(@) but less than 90^(@) is called an acute angle.

Prove the following identity,where the angles involved are acute angles for which the expressions are defined.(cos A-sin A+1)/(cos A+sin A-1)=cos ecA+cot A

Prove the following identity,where the angles involved are acute angles for which the expressions are defined.(iv) (1+sec A)/(sec A)=(sin^(2)A)/(1-cos A)

Prove the following identity,where the angles involved are acute angles for which the expressions are defined.(vi) sqrt((1+sin A)/(1-sin A))=sec A+tan A

Prove the following identity,where the angles invorved are acute angles for which the expressions are defined.(ii) (cos A)/(1+sin A)+(1+sin A)/(cos A)=2sec A

The complement of an acute angle is ............
