The answer is -3. Now I just got 100 points!!!
Answer:
C or A
Step-by-step explanation:
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
° .
Well since the line is headed to the left side, you know it has a negative slope, so B and C can be crossed out. Then, you know that point-slope form is written as y - y1 = m (x - x1)
So, you just plug in the numbers given on the graph, (4,-2)
You should come out with y + 2 = -2 (x - 4)
And that's the equation of the line in point-slope form!!! :)
Hope it helped and you understand it better!
D.) y + 2= -2 (x - 4)
