Answer:

5:2

Step-by-step explanation:

18 and 45 are both multiples of nine, so I divided both sides by nine.

18/9 = 2

45/9 = 5

5 and 2 are prime numbers, so you can't simplify any further.

The rate of change in this pattern is 2:1 comparing the change in 'y' to the change in 'x'.. this means that if you go form 33 to 51 ( an increase of 18), then the the increase from 16 to ? will be 9. Therefore, ? = 16 + 9 or 25
? = 25

How to find variables x- and y-

Monica [59]

It says that the triangles are congruent (same size). Also, a triangle's angles add up to 180 degrees. In both of these triangles, one angle is 90° and another angle is 52°. The other angle is 180°-90°-52°=38°.

Solve these equations to find x and y: 2x+18=38, 3y+11=38

$2x+18=38\\2x=20\\x=10$
