Question

Look at the figure:

The figure shows two right angle triangles have a common side AC. Triangle ABC has length of BC 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 cos x° = tan y°

2 sin x° = tan y°

2 sin x° = cos y°

2 tan x° = sin y°

Answer 1

I think C, but I am not sure :(

Answer 2

Ugh lol thanks anyway!

Answer 3

yw haha

Answer 4

can you help witht his one?
The figure shows a right triangle AEB on a rectangle CBED.

The figure shows a rectangle CBED. The diagonal BD of the rectangle is drawn. The length of side CD is 30 centimeters and the measure of angle BCD is 90 degrees and the measure of angle DBE is 30 degrees. There is a right triangle AEB on the side BE of the rectangle. Triangle AEB has the measure of angle AEB equal to 90 degrees and the measure of angle ABE is 30 degrees.

What is the length of side AD?

19.23 cm

24.32 cm

34.64 cm

30.16 cm
