and 
Step-by-step explanation:
Recall that
is a value of the function cosine for the special angles:
and
, then:

Answer:
12°
Step-by-step explanation:
a right triangle implies there is an angle that is 90°
another angle is 78°
the third angle is 180 - (90 + 78) = 180 - 168 = 12°
Answer:
15 degrees
Step-by-step explanation:
2.5x6= 15
Answer: The number is 15
Step-by-step explanation: basically the equation you should solve is
(x)+(2x)+(2x+7)=82
5x+7=82
5x= -7+82
5x=75
5/5x=75/5
x=15
