Question

1. Considering each pair of triangles similar, calculate the unknown.dont ans if you dont know otherwise you'll be reported!!​

Answer 1

Answer:

a=12 and b=4

Step-by-step explanation:

Since, the triangles are similar, we can write:

$\dfrac{a}{4} = \dfrac{15}{5}\\\\\rightarrow a=12$

Those are the sides opposite to the 30 degree angle in both the triangles.

Also,

$\dfrac{12}{b} = \dfrac{15}{5}\\\\\rightarrow b=4$

Those are the bottom sides of the triangles.
