Answer:
It invaluatesa to 1
Step-by-step explanation:
sin25 ∘cos65 ∘+cos25 ∘sin65 ∘=sin25
∘ sin(90 ∘−65 ∘)+cos25
∘cos(90 ∘−65 ∘ )
=sin25 ∘
sin25 ∘ +cos25 ∘cos25 ∘
=sin 2 25 ∘+cos 2 25 ∘=1

Answer:

Step-by-step explanation:
Use the acronym SOH-CAH-TOA
sin = 
So opposite is 3 and hypotenuse is 4.
tan = 
So opposite is -3 and adjacent is 4.
cos = adjacent/hypotenuse
cos = 
Answer:
y = 3x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
12x - 4y = - 8 ( subtract 12x from both sides )
- 4y = - 12x - 8 ( divide all terms by - 4 )
y = 3x + 2 ← in slope- intercept form
