Answer:
∠ VXU = 105°
Step-by-step explanation:
the chord- chord angle VXU is half the sum of the arcs intercepted by the angle and its vertical angle.
The sum of the arcs in a circle = 360° , so
UV = 360° - (130 + 60 + 90)° = 360° - 280° = 80°
Then
∠ VXU =
(80 + 130)° = 0.5 × 210° = 105°

Answer:
Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
= 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
= 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
= 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8
Plugin x = 20 in the equation
y = 20 - 7
y = 13
