Answer 2

Answer:

The second smallest angle is $67.38$°.

Step-by-step explanation:

Given: The triangle is a right angle triangle with the sides $5, 12 ,13.$

To find: The objective is to find out the second smallest angle of the triangle.

The given right-angled triangle with sides of $5$, $13$, and $12$.

Let B be the right-angle.

Consequently, $\frac{5}{sinA}=\frac{13}{sinB} =\frac{12}{sinC}$

Now,

$sinA= 5.\frac{sin90}{13}\\ =0.3846.$

As a result,∠$A=22.16$°.

$C=90-22.16\\ =67.38.$

Therefore, the second smallest angle is:$67.38$°.
