The sides of the triangle are 3x, 4x and 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5
first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm

Answer:
x=-7
Step-by-step explanation:
If a line is parallel to the y-axis, then it is vertical because the y-axis is vertical.
A vertical line is in the form of x=a number.
Since the line we are looking for is 7 units to the left of the y-axis, then the line is x=-7. -7 is 7 units left of 0.
7 units right would have been x=7.
