Sagot :

Answer:

C. 145

Step-by-step explanation:

180 - 90 - 55 = 35

180 - 35 = 145
C. 145
Your first step is to solve for the missing angle in the top triangle. You were given the two angles 55 and 90 so you add those together and subtract from 180 to get the missing angle. The angle you got will be equal to the angle next to X to find ask you subtract that number from 180 and that will give you X = 145
