Answer:

48° or 138°

Explanation:

$\displaystyle Complementary\:Anlges\:[Sum\:up\:to\:90°] \\ Supplementary\:Angles\:[Sum\:up\:to\:180°]$

$\displaystyle 90° = 42° + m∠4 \: \: \: \: \: 180°= 42° + m∠4$

$\displaystyle 48° = m∠4 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 138° = m∠4$

I am joyous to assist you anytime.
