In angle XYZ, m/_ y=80, XY= 14, and XZ=17. to the nearest tenth, what is m/_ z

Using Sine rule we found the measure of ∠°.    

Step-by-step explanation:

Diagram of the given condition shown below.

Given that,

In Triangle Δ,

       ∠°  ,  .

To find :- What is the measure of ∠.

So,

Using Sine rule :-  sine rule relates the sine of each angle to length of        opposite side.

                                                Where,    are angles of triangle Δ

                                                                     are side length of triangle.

Then,      

Using cross multiplication:-

  ⇒            

  ⇒                

  ⇒                

  ⇒                      ∠

  ⇒                     ∠°

Hence,

Using Sine rule we found the measure of ∠°.          

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
