Decide whether the pairs of triangles are similar, give reasons.

Both triangles are similar

Step-by-step explanation:

Triangles are similar if their 3 angles are equal each other. First 2 triangles are similiar becuase both triangles have angles 60*,15*, and if the 2 angles are equal then the third is equal too. If triangles are similar then the proportions must be the same. 18/12=9/6 ` the proportion is kept and one angle is equal thus they are similar too.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
