The COsine is the COmplementary trigonometric function of the sine. Remember what complementary angles are? They are angles which add up to 90º. So if you take the sine of a certain angle, it is equal to the value of the cosine of that complementary angle. For example, sin(30º)=cos(60º), because 60º is the complementary of 30º.
Answer:
135 degrees \
Step-by-step explanation:
5x= x+108
Subtract x from the right
4x= 108
divide by 4
x= 27
Substitute for x in the original equation
(x+108)
(27)+(108)
= 135 degrees
The third option
