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°

Answer:
(X+9)(X+8)=0
X=-9,-8
Step-by-step explanation:
x^2+ 17x-12=-84
x^2+17x-12+84=0
x^2+17x+72=0
x^2+(9+8)X+72=0
x^2+9x+8x+72=0
X(X+9)+8(X+9)=0
(X+9)(X+8)=0
X=-9,-8
So the value of the X is -9,-8
