Are there multiple choice options??
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°
Ok for example let’s use 2 as the slope. You are going to put the 2 over 1 so it will look like this 2/1. And that would be your slope!
