F(r) = 60 - 2/3r r = 12
Substitute r for 12
f(12) = 60 - 2/3(12) 12 * 2/3 = 8
f(12) = 60 - 8
f(12) = <u /><em><u>52</u></em><em><u /></em>
52 is your answer

4w=-8
/4 /4
w=-2
Check the picture below.
notice that 146° is sitting on a flat-line, and thus it has a sibling linear angle, namely 34°.
now, recalling that a triangle has a sum of 180° for all interior angles, the missing one is 126°, and incidentally that is a corresponding angle with "c".
