Answer:
x = 25
Step-by-step explanation:
Noting that these figures are similar, we set up and solve an equation of ratios:
x 30
---- = ------
15 18
Cross multiplying, we get:
18x = 30(15), or 3x = 5(15) = 75. Then x must be 25.
The answer is A.27 it is 9 * 3 is how you get it
It's the same as adding 2 fractions the product of 2 rational numbers is rational
Answer:
x = 15
Step-by-step explanation:
Assuming you require the value of x
The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is
9(9 + x) = 8(8 + 19), that is
81 + 9x = 8 × 27 = 216 ( subtract 81 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
