What is the measure of the highlighted (middle) angle, in degrees?

Step-by-step explanation:

5x + 2x + 67.3° = 180° { being linear pair }

7x = 180° - 67.3°

7x = 112.7°

x = 112.7°/7

x = 16.1°

Now

5x = 5 * 16.1 = 80.5°

Hope it will help :)

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
