whats the value of x

A 95

B 105

C 75

D 85​

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

Answer:

85 degrees

Step-by-step explanation:

All angles in a triangle must add up to 180, so we can set up an equation

x+40+55=180

Now all we need to do is to subtract 40 and 55 from both sides

x+55=180-40=140

x=140-55=85

x=85
