(b) Find the measure of ZABC to the nearest degree.

The diagonals are AC = 16 and DB = 30

We must determine the rhombus altitude

altitude = AC * DB / (2 * side)

altitude = 16 * 30 / (2 * 17)

altitude = 14.1176470588235

arc sine (angle D) = opp/hyp = 14.1176470588235 / 17

arc sine (angle D) = 0.83044982698962

angle D = 56.145 degrees

In a rhombus, Angle D = Angle B so Angle B = 56.145

In a rhombus, the diagonals bisect the angles so

Angle ABC = 56.145 / 2 = 28.0725 Degrees

Step-by-step explanation:

answer: 20

step-by-step explanation: subtract the minimum date value from the maximum data value to find the date range. in this casem the date range is 42 - 22 = 20
