Answer:
The slope of the line segment CD = 9
Hence, option 'D' is true.
Step-by-step explanation:
Given that the slope of line segment = 9
- We know that two triangles would be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given that the line segments AB and CD are both parts of the same non-vertical line. It means their slopes must be the same.
Thus, the slope of the line segment CD = 9
Hence, option 'D' is true.
Answer:
look it up my guy
Step-by-step explanation:
Add the 75 and 79 which gives u 154
then subtract it by 180 and should give you 26 as your final answer
The values would be
sin2x = -3/5
cos2x = -4/5
tan2x = 3/4
What are double angles in trigonometry?
The double angle formulas are used to find the values of double angles of trigonometric functions using their single angle values. For example, the value of cos 30° can be used to find the value of cos 60°. Also, the double-angle formulas can be used to derive the triple-angle formulas.
Given: tanx = -3
Now as we know,

Now

And similarly, we can find the value of tan2x, as
tan2x = sin2x/cos2x
= (-3/5)/(-4/5)
= 3/4
Hence,
The values would be
sin2x = -3/5
cos2x = -4/5
tan2x = 3/4
