Angle x is an acute angle in a triangle. if cos x=4/5, then the sin x=

Step-by-step explanation:

Angle x is an acute angle in a triangle.

The measure of cosine angle is given to be :

Now, we need to find the measure of the sine angle for the same triangle.

⇒ Base = 4 units and Hypotenuse = 5 units

So, Length of perpendicular = 3 units ( By using Pythagoras theorem)

move it to the other side

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
