Step-by-step explanation:

78 + 54 = 132

C. 40.8

Step-by-step explanation:

Looking at the pic we could see that angle x which is the missing angle is opposite the height which is 49.2  and is adjacent to the distance between the two birds which is 57.4. So using soh cah toa  we could define it as  the inverse of tan which is opposite over adjacent.

we could write the formula  

m∠x =      

m∠x = 40.8306   which rounds to 40.8
