Answer:
19/24m-1/3
Step-by-step explanation:
1/6m-(-5/8m+1/3)=1/6m+5/8m-1/3=4/24m+15/24m-1/3=19/24m-1/3

Answer:
0
Step-by-step explanation:
Using the trigonometric identity
cotx =
Given
3cotθ = 2 , then
3 = 2 ( multiply both sides by sinθ )
3cosθ = 2sinθ ( subtract 3cosθ from both sides )
2sinθ - 3cosθ = 0
Thus
=
= 0
Answer:
Answer: The line segment joining the mid-points of two sides of a triangle is parallel to the third side. .
Step-by-step explanation:
You can prove this theorem using the following clue: Observe the figure in which E and F are mid-points of AB and AC respectively and CD || BA. So, EF = DF and BE = AE = DC.
Do you remember what the sine of an angle is ? If the angle is in a right triangle, then the sine of the angle is (the opposite side) divided by (the hypotenuse). So in this triangle, sin(38) = 24/x . And. X = 24/sin(38) . You can find sin(38) with your calculator or on line, and once you have that number, you're just a simple division away from knowing 'x'.
