  8. (d)  19

  9.  94°

Step-by-step explanation:

8. The similarity statement tells you corresponding sides are proportional.

  CB/CA = FE/FD

  g/9 = 95/45

  g = 9(95/45) = 9(19/9)

  g = 19

9. The similarity statement tells you ∠J ≅ ∠M.

  ∠M = 180° -∠P -∠K = 180° -32° -54° = 94°

  ∠J = 94°

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
