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.

the missing angle is  ° .

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  :

⇒

In question we have following parameters as :

Putting these value in   we get :

⇒  

⇒  

⇒  

⇒  

⇒  °

Therefore , the missing angle is  ° .

you never say the total so we cant find the percentage used for petrol
