Can someone PLEASE help?? asap

Step-by-step explanation:

sin(s+t) = sin(s)+cos(t) which results

(sin(s)×cos(t))/(cos(s)cos(t)) + (cos(s)×sin(t))/(cos(s)cos(t))

knowing that tan=sin/cos and that cos/cos=1 and sin/sin=1

resulting tan s ×1 + tan t × 1 = tan s + tan t

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
