the missing angle is ° .
<u>Step-by-step explanation:</u>
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 ° .
