Answer:

x=18

Step-by-step explanation:

(6x+3)+(3x+15)=180

(6x+3x)+(3+15)=180

9x+18=180

    -18  -18

9x=162

162/9

x=18

These two angles should sum to 180 since they form a line. So 6x+3+3x+15=180. 9x=162. x=18.

The ratio of the measures of the angles of a triangle is 4:6:8. Find the measure of the largest angle.
garri49 [273]

Answer:

80°

Step-by-step explanation:

The angles can be written as 4x, 6x, and 8x. Since the sum of angles in a triangle is 180 degrees we can write:

4x + 6x + 8x = 180

18x = 180

x = 10 which means the largest angle (8x) = 8 * 10 = 80°

X = 5 boxes

<u><em>figure out the X for each person</em></u>

  • Lizzy = 5 X

<u>Lizzy sold</u>: 5 * 5 = 25 boxes

  • Suzy = 1 X

<u>Suzy sold</u>: 5 * 1 = 5 boxes

  • John = 3 X

<u>John sold</u>: 5 * 3 = 15 boxes

  • Mark = 8 X

<u>Mark sold</u>: 5 * 8 = 40 boxes

  • Lamar = 4 X

<u>Lamar sold</u>: 5 * 4 = 20 boxes
