3 times the complement of an angle is 30 more than the supplement of the original angle. What is the measure of the angle? 15° 3
labwork [276]
1. By definition, the sum of the Suplementary angles is 180° and the sum of the Complementary angles is 90°. Keeping this on mind, you have:

 90-x (The complement of the angle)
 180-x (The sumplement of the angle)

 "x" is the angle that you want to calculate.

 2. Then, you have:

 3(90-x)+30=180-x
 (270-3x)+30=180-x
 300-3x=180-x
 300-180=-x+3x
 120=2x
 120/2=x
 x=60°

 What is the measure of the angle?</span> 

 The answer is: The measure of the angle is 60°.

dalvyx [7]

Answer: I believe the answer would be $42,890.80 is the total annual(yearly value) of Almas job.

Step-by-step explanation: First you need to figure out that $19.20 x 37= $710.40(hourly wage per week). Then, you need to figure out that $710.40 x 52 = $36,940.80(the weekly wage x the 52 weeks in the year). Next, add the yearly medical coverage. $5,500 + $36,940.80 = $42,440.80. Now, you know that 1/2 of the dental is going to be $350 and 1/2 of the life insurance is going to be $100. Add those to your previous balance. $42,440.80 + 350 + 100 = 42,890.80.
