2 answers:
Answer:
<h2><u>m∠D = 60°</u></h2>Step-by-step explanation:
Use the CAH from SOHCAHTOA.
CAH is cosΘ =
Substitute the given values into the above formula.
The adjacent side of ∠D measures 8, and the hypotenuse (the longest side of the right triangle) measures 16.
cosΘ =
cos D =
D = (
)
D = 60°
Therefore, the m∠D = 60°

Answer:
Just took the test,
1)d, 3
2)a, -13
3) c, y=-2x+6
4) c, f'(a)=8a+2
Step-by-step explanation:
For #3, graph f(x)=-x^2+5. Next graph y=-2x+6. You will see that the added equation touches at exactly the point (1,4). this make it the tangent line equation
