Question

Look at the figure:

The figure shows two right angle triangles have a common side AC. Triangle ABC has length of BA equal to 5 centimeters, the measure of angle ABC is 90 degrees and the measure of angle BAC is x degrees. Triangle ACD is a right triangle with angle DAC equal to 90 degrees, angle ACD equal to y degrees and AD equal to 10 centimeters.

Based on the figure, which equation is true?

2 sin x° = tan y°

2 sin x° = cos y°

2 tan x° = sin y°

2 cos x° = tan y°

Answer 1

the last one

Answer 2

sinx =5/10 = 1/2
tan y = 10/10 =1
2 sin x =tan y

Answer 3

@cj49 sinx =\(\dfrac{OPPOSITE}{hypotenuse}\) , not \(\dfrac{adjacent}{hypotenuse}\)

Answer 4

so that, your answer is not .... good enough. :)

Answer 5

yes sorry its d last one.
