The common factors of 30 and 42 are 1, 2, 3, and 6.
The greatest common factor is 6.
4x+12-5x-30=-x-18
One third of 18 is 6. 6 goes into 18 three times - 6 + 6 = 12, 12 + 6 = 18.
The longest side of the triangle will always be opposite the largest angle, which is 90° in this case. We can use the sine law to work out the other sides with that: sin(90°) / 18 = sin(60°) / x = sin(30°) / y 1/18 = sin(60°) / x x = 18 sin(60°) x = 18√3 / 2 x = 9√3 1/18 = sin(30°) / y y = 18 sin(30°) y = 9 So the triangle has a sides of 9 and 9√3, with a hypotenuse of 18

The common factors of 30 and 42 are 1, 2, 3, and 6.
30
18 goes into 100 5.56 times. The easiest way to find this answer is to simply divide 100 by 18 to get your answer of 5.56.
288/30= 9.6 30 can go into 288 9.6 times
