AB = 17 m, AC ≈ 19.2 m

Step-by-step explanation:

Drawing a line from A to the base creates a right triangle

with legs 8 and (25 - 10 ) = 15

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )

AB = = 17 m

------------------------------------

Using Pythagoras' identity i right triangle ABC

AC² = AB² + BC² = 17² + 9² = 289 + 81 = 370 ( take square root of both sides )

AC = ≈ 19.2 m ( to 1 dec. place )

i think this could be a possible answer (1 / 84) -1

good luck! : d

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
