Let $M$, $N$, and $P$ be the midpoints of sides $\overline{TU}$, $\overline{US}$, and $\overline{ST}$ of triangle $STU$, respectively.  Let $\overline{UZ}$ be an altitude of the triangle.  If $\angle TSU = 62^\circ$ and $\angle STU = 29^\circ$, then what is $\angle TMP + \angle TUZ$ in degrees?

Note that TMPTUS. Then TMP=TUS=180TSUSTU=89.

 

Considering the interior angle sum in triangle TUZ gives 

90+STU+TUZ=180TUZ=90STU=61

 

Therefore,

TMP+TUZ=89+61=150
