Answer:

 m∠F = 140°

Step-by-step explanation:

Let's recall that the interior angles formed by the sides of a hexagon have measures that sum to 720°.

Therefore:

130 + 120 + 110 + (x - 20) + (x - 60) + (x - 40) = 720

360 + x - 20 + x - 60 + x - 40 = 720

3x = 720 - 240

3x = 480

x = 160

What is the measure of angle F?

m∠F = 160 - 20

 m∠F = 140°

A bouquet of flowers contains a total of 24 red and white roses. The number of red roses is 4 less than three times the number o

geniusboy [140]

Answer:

White roses - 7

Red roses - 17

Step-by-step explanation:

Set up proportional equations

White roses = x

Red roses = 3x - 4

Set equal to 24

x + 3x - 4 = 24

4x - 4 = 24

4x = 28

x = 7

x is white roses, so there are 7

Plug x value into red rose equation

3(7)-4

21-4 = 17 red roses

Check

17+7 = 24
