If the measure of an angle is 27°,find the measure of its supplement.
finlep [7]

Answer:

153°

Step-by-step explanation:

1. If 27° is the supplement of another angle (or vice versa), that means both angles add up to 180.

2. To find the supplement of 27°, we simply subtract that number from 180.

  • 180 - 27
  • 153

Therefore, the supplement of 27° is 153°.

Sauron [17]
You just find out what the missing variable is by subtracting 88 from 107 on the first one. You do the same for the last too as-well, but just insert the numbers that they say.
