Answer:
∠ A = 50°
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary, sum to 180°
∠ A + 130° = 180° ( subtract 130° from both sides )
∠ A = 50°
Answer:
arc TSR = 180°
arc US = 110°
arc RU =130°
∠RPQ = 60°
arc QRT = 240°
arc UTQ = 290°
Step-by-step explanation:
arc TSR = 180° because half circle
arc US = 110° because 50° + 60°
arc RU =130° because 180° + 50°
∠RPQ = 60° because vertical to 60°
arc QRT = 240° because 180° + 60°
arc UTQ = 290° because 360° - 70°

Answer:
y = -2x + 1
Step-by-step explanation:
y = mx + c
m = -2
y = -2x + c
x = -1, y = 3
3 = -2(-1) + c
3 = 2 + c
3 - 2 = c
c = 1
y = -2x + 1
