Answer:

X = 24

Step-by-step explanation:

Since the two triangles are similar such that one is twice the other, twice of 9 is 18; and thus twice of 12 equals 24.

Answer:

x = 20

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{x}{12}$ = $\frac{15}{9}$ ( cross- multiply )

9x = 180 ( divide both sides by 9 )

x = 20

Make a ten or hundred to add mentally 198+132

Veseljchak [2.6K]

2000. Because if you add the 2 it will make 1200, 2+8 is 10 so you carry the 1, and 3+9 is 12 then you add the 1 you got from 10 and you have 13. then you add 1+1 and get 2 and add the 1 you got from 13 so there you have it.
