Answer:
(-2,0) and (-4,-2)
Step-by-step explanation:
The solution to the system of equations is where the two graphs cross
They cross at (-2,0) and (-4,-2)
Your answer is C c:
First, split the angle into two angles where the values of the six trigonometric functions are known. In this case, 105, can be split into 45+60 (cos (45+60))
Use the sum formula for cosine to simplify the expression. The formula states that cos (A+B) = - (cos (A) cos (B) + sin (A) sin (B)).
The exact value of cos(60) is 1/2. So multiply 1/2 to cos (45) - sin (60) times sin (45).
The exact value of cos (45) is the square root of 2 over 2
(1/2) ⋅ (<span>√2/</span>2) - sin (60) <span>⋅ sin (45)
</span>
Value of sin (60) is <span>√3/2
</span>(1/2) ⋅ (√2/2) - √3/2 ⋅ sin (45)
exact value of sin (45) is √2/2
(1/2) ⋅ (√2/2) - √3/2 ⋅ √2/2
all that equals √2/4 - √6/4
We need to see the answer choices.
