Answer:
x = 15
Step-by-step explanation:
We need to find the value of x in the equation 3x – y = 18 when y = 27.
To find the value of x, put y = 27 in the above equation.
So,
3x - 27 = 18
3x = 45
x = 15
So, the value of x is 15.
Step-by-step explanation:
x + 2x + 3x = 180°
6x = 180°
Therefore, x = 30°
2 x = 60°
3x = 90°
Hence, it is a right angled triangle.
