Answer:

36 units ⇒ Answer 1 is correct

Step-by-step explanation:

To find the perimeter of a triangle you have to simply add the 3 sides together.

They have given the lengths of three sides as follows.

9 , 12 , 15 units

Let us solve now.

Perimeter = 9 + 12 + 15

= 21 + 15

= 36 units

Hope this helps you :-)

Let me know if you have any other questions :-)

Given:

A right angle triangle ABC, right angled at C.

To find:

The measure of θ.

Solution:

In a right angle triangle,

$\tan \theta=\dfrac{Opposite}{Adjacent}$

In triangle ABC,

$\tan \theta=\dfrac{AC}{BC}$

$\tan \theta=\dfrac{2.7}{5}$

$\tan \theta=0.54$

It can be written as

$\theta=\tan^{-1}0.54$

$\theta\approx 28.369$

Therefore, the measure of θ is 28.369.
