Question

Can someone please help me with this math problem:)

Answer 1

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 2

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
