PLEASE HELP!! PICTURE INCLUDED!!<br><br> Please explain how to find angle R!!
mafiozo [28]

Answer:

∠ R = 75°

Step-by-step explanation:

you are correct with answers to a, b, c

d

the sum of the 3 angles in Δ QRS = 180° , that is

∠ Q +∠ R + ∠ S = 180° , so

55° + ∠ R + 50° = 180°

∠ R + 105° = 180° ( subtract 105° from both sides )

∠ R = 75°
