The lengths of sides of second triangle are:
10cm, 18cm and 22cm
Step-by-step explanation:
Given
Ratios of sides of triangle=> 1:2
Given sides of a triangle:
5cm,9cm and 11 cm
The ratio 1:2 means that for each 1 cm in first triangle, there are 2 cms in seconds triangle. This simply means that the sides of the second triangle are double of the first triangle.
So,
The sides of the second triangle are:
Hence,
The lengths of sides of second triangle are:
10cm, 18cm and 22cm

y= -5
Multiply both sides by 3
you get (2y−27=6y+9)
Subtract 2y from both sides
Simplify 6y+9−2y to 4y+9
Subtract 9 from both sides
Simplify −27−9 to −36
Divide both sides by 4
Simplify 36/4 to 9
Then switch the sides to get,
y= -9
