Identify the function family of the following function:

f(x) = 4|x| - 3

Angle M equals 60

The triangles are similar and the angles are congruent to their counterpart.

Triangle TKM is similar to triangle DAJ.
This mean angle T is congruent to angle D. Angle K is congruent to angle A and angle M is congruent to angle J.

Since triangle angles add to 180, and we know two of the angles, we can form an equation to find the third angle.

On both triangles :

Angle T and D add right angles as indicated by the square box. Right angles equal 90.

So we have:
90+30+x=180
120+x=180
Subtract 120 from each side to solve x and you end up with
X= 60

Angle M and Angle J each equal 60.
