Hello!! So any time a question says "What percent" you can immediately write down the fraction X/100. The proportion would be 15/20= x/100. Then cross multiply to get the equation 1,500=20x. Divide both sides by 20 and x equals 75! Hope this helps!

Step-by-step explanation:

27x² = 3*3*3*x*x

45x³y² = 3*3*5*x*x*x*y*y

Now

GCF = 3 * 3 *x * x = 9x²

How do you find the angle measure?
yulyashka [42]

Answer:

∠ XYZ = 41°

Step-by-step explanation:

∠ XYZ = ∠ 3x + 20 ( corresponding angles ) , thus

8x - 15 = 3x + 20 ( subtract 3x from both sides )

5x - 15 = 20 ( add 15 to both sides )

5x = 35 ( divide both sides by 5 )

x = 7

Thus

∠ XYZ = 8x - 15 = 8(7) - 15 = 56 - 15 = 41°
