I think it’s -0.75. The x coordinate represents the term number so y would show the pattern which is -3.75, -4.5, -5.25, -6, -6.75, -7.5, -8.25, -9. To get to the next number, each term is being decreased by 0.75. Hope this helps :)

Describe how you would find the third angle measure in a triangle knowing that one angle measures 63 degrees and the the other m

maxonik [38]

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 :

⇒ $a+b+c=180$
