The y value of I is (5(2) + 3(5))/(3 + 5) = (10 + 15)/8 = 25/8 = 3.125
8-4x=9
-4x=9-8
-4x=1
X=-1/4
X=-0.25
Answer:
D. 85
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180. Since we already know 2 of the interior angles of that triangle (40 and 55), we can subtract those two angles from 180 to find x.
180 - 40 - 55 = 85
the other asnwers dont make any sense. but just take my word for it.
