The angle supplementary to x and 3x are equal.
Supplementary angles = 180
Solution
x + 3x = 180
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
The angle supplementary to x is 3x
3x = 3*45
3x = 135
This angle is vertically opposite y. Vertically opposite angles are equal. So y = 135
Answer
x = 45
y = 135

Step-by-step explanation:
3 x 6 x 9 x 3 x 6 x 9 = ?
3 x 6 = 18
18 x 9 = 162
162 x 3 = 486
486 x 6 = 2,916
2,916 x 9 = 26,244
3 x 6 x 9 x 3 x 6 x 9 = 26,244

Answer:
The total population of the school is 300 students.
Step-by-step explanation:
Considering, we are working with percentage we can use the equation:
y = %x.
To fill in the equation you can use what you already know, 60% = 180
180 = 0.60x
To solve this, you can then divide both sides of the equation by 0.60. This will then give you your answer, 300 = x.
For checking, you can do 180 = 0.60(300) which will result in 180 = 180.
