Question

Describe how you would find the third angle measure in a triangle knowing that one angle measures 63 degrees and the the other measures 48. Then tell e what the missing angle measure must be.

Answer 1

the missing angle is  $c=69$° .

Step-by-step explanation:

Here we have , a triangle knowing that one angle measures 63 degrees and the the other measures 48. We need to tell e what the missing angle measure must be. Let;s find out :

We know that , by the property of triangle : Sum of all the three angles of a triangle is always 180° . Let angles of triangle be a,b,c  :

⇒ $a+b+c=180$

In question we have following parameters as :

$a=63\\b=48\\c=?$

Putting these value in  $a+b+c=180$ we get :

⇒  $a+b+c=180$

⇒  $63+48+c=180$

⇒  $111+c=180$

⇒  $c=180-111$

⇒  $c=69$°

Therefore , the missing angle is  $c=69$° .
