138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42
19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29
Answer:
X = 15
Step-by-step explanation:
We can tell that the two sides that show the degrees are equal because of the arc. We can set up a simple equation:
x + 45 = 60
x = 15
You will save $9
Convert 20% to decimal
Each % is 0.01 so 20×0.01=0.2
Then multiply
45×0.2=9
Answer: 8/3
