he photo shows a triangle island. A appropriate triangle is shown with an acute angle same to 50 degrees. The size of the side of the triangle opposite come the acute angle is x. The size of the next of the triangle surrounding to the acute angle is y. The size of the hypotenuse is z.Which expression shows the value of z?Answerx cos 50°x sin 50°y/sin50y/cos50

If you execute not know the trig functions really well, watch this http://www.khanacademy.org/math/trigonometry/v/basic-trigonometry to answer the question, you must write under the definitions of sin(50), cos(50), tan(50) and then solve for z=then look for the answer.

You are watching: Which expression shows the value of z?

Look at the locations L, M, and N top top the roadway map shown below. LMN is a best angle triangle v measure of angle LMN equal to 90 degrees and also the measure up of angle LNM same to 75 degrees. The length of segment NM is 8 miles.What is the distance in between location L and also location M?8/sec 758/cot75sec75/8cot75/8

please help, and show how thank you two ropes, advertisement and BD, room tied to a peg on the soil at point D. The other ends of the ropes room tied come points A and B ~ above a flagpole as presented below. 2 ropes, ad and BD, space tied come a peg ~ above the soil at allude D. The various other ends of the ropes are tied come points A and B top top a flagpole. Angle ADC actions 60 degrees and also angle BDC actions 45 degrees. The length of DC is 9. Angle ADC measures 60° and angle BDC steps 45°. What is the distance in between the point out A and also B top top the flagpole? price 1.73 feet 2.56 feet 4.32 feet 6.59 feet
