Question

If measures of two of the direction angles of a vector are 45" and 60°. Find
measure of third angle.​

Answer 1

Answer:

75°

Step-by-step explanation:

subtract from 180 ,

180-105 = 75

Answer 2

Step-by-step explanation:

Let two vectors = 45 and 60

Total vectors = 45 + 60 = 105

We know that sum of interior angles = 180

45 + 60 + Third angle = 180

105 + third angle = 180

Third angle = 180 - 105 = 75
