Q: THE PERPENDICULAR SIDES OF A RIGHT ANGLED TRAINGLE ARE 12 AND 15 CENTIMETERS LONG. ANOTHER RIGHT ANGLED TRAINGLE OF THE SAME AREA HAS ONE AT THE PERPENDICULAR SIDE 18 CENTIMETERS LONG . WHAT IS THE LENGTH OF THE OTHER ??

Area of a right triangle is 1/2 x height x base

The area of the first triangle is 1/2 x 12 x 15 = 90 square cm.

The area of the other triangle is 90 and one side is 18:

90 = 1/2 x 18 x S

Multiply both sides by 2:

180  = 18 x S

Divide both sides by 18:

S = 180/18

S = 10

The length of the other side is 10 centimeters

step-by-step explanation:

goog be able to you with that maybe

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
