Classify the triangle with angles measuring 21, 69 and 90

Right angled and a scalene triangle

step-by-step explanation:

A right angled triangle is a triangle that has one of its angles to be 90°.

A scalene triangle is a triangle that has all his angles and sides to be different.

Based on the angles of the triangle given i.e 21°, 69° and 90°, the triangle can be classified as a RIGHT ANGLED TRIANGLE because it contains 90° as one of its angles.

The triangle is also classified as a SCALENE triangle because all the angles of the triangle are different i.e no two or three of the angles are the same.

you need to give us more information since we can't answer

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
