Figure VWYX is a kite.
Pachacha [2.7K]

Answer:

∠VXY = 74°

Step-by-step explanation:

The sum of the 4 interior angles of a kite = 360°

Sum the 4 angles and equate to 360

90 + 18x - 2 + 90 + 12x + 2 = 360 ← simplify left side

30x + 180 = 360 ( subtract 180 from both sides )

30x = 180 ( divide both sides by 30 )

x = 6

Hence

∠VXY = 12x + 2 = (12 × 6) + 2 = 72 + 2 = 74°

? Question

Answer:

Please find attached , the filled in boxes

The y-intercept is (0, 4)

Step-by-step explanation:

The given function is g(x) = 4 \times (0.6)^x

The values of x are given as -10, -1, 0, 1, 2, 8

The values of g(x) are

g(-10) = 4 × 0.6⁽⁻¹⁰⁾ = 4 × (3/5)⁽⁻¹⁰⁾ = 4 × (5/3)⁽¹⁰⁾ = 661.53

g(-1) = 4 × 0.6⁽⁻¹⁾ = 4 × (3/5)⁽⁻¹⁾ = 4 × (5/3)⁽⁽¹⁾ = 20/3 =

g(0) = 4 × 0.6⁽⁰⁾ = 4 × (3/5)⁽⁰⁾ = 4 × 1 = 4

g(1) = 4 × 0.6⁽¹⁾ = 4 × (3/5)⁽¹⁾ = 12/5 = 2.4

g(2) = 4 × 0.6⁽²⁾ = 4 × (3/5)⁽²⁾ = 36/25 = 1.44

g(8) = 4 × 0.6⁽⁸⁾ = 4 × (3/5)⁽⁸⁾ = 0.0672

The y intercept is given at the point x = 0 which is g(0) = 4

The y-intercept is g(0) = 4
