Question

If an angle is 30° less then it's complement ; find it's measure . ​

Answer 1

Answer:

3o degrees

Step-by-step explanation:

x-30 is 90 degrees.

30 degree

60-30=30 degrees.

Answer 2

Answer:

measure of the angle is 75°

Step-by-step explanation:

Let the measure of the angle is x.  

Two angle are supplement if they adds to 180 degrees.  

Therefore, the supplement of the angle x is (180-x)  

Now, it has been given that measure of an angle is 30 degree less than its supplement.  

Thus, we have  

x = 180 - x - 30  

Solve the equation for x  

2x = 150  

x = 75°  

Therefore, the measure of the angle is 75°
