Acronym to remember the 3 basic trigonomic functions: 

Soh - Cah - Toa 

             opposite
sin = --------------------
            hypotenuse

              adjacent 
cos = -------------------
             hypotenuse

             opposite 
tan =  -----------------
             adjacent 


In your case, you can set up a sine trigonomic function, like this: 

Sin 48 = 10      (adjacent)
               -----  
                 x       (hypotenuse)

                       10
 (x) Sin 48 = ------ (x)
                         x

  (x) Sin 48 = 10 
 --------------   ------------- 
  Sin 48         Sin 48 

Plug in 10(sin)(48) into a calculator.

x = 7.43


I just realized that you didn't ask me to find the answer, but now you will know even more than you need to :D

The pair of triangles that are congruent by the ASA criterion is . The pair of triangles that are congruent by the SAS criterion
anzhelika [568]

Answer:

The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ.

The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.


Step-by-step explanation:

Two triangles are congruent by ASA property if any two angles and their included side are equal in both triangles .In triangles Δ ABC and Δ XYZ the equal side 5 is between the two equal angles. So these triangles are congruent by ASA criterion.

Two triangles are congruent by SAS if  two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle .In triangles  Δ BAC and ΔRQP. the included angles A and Q are equal and hence the triangles are congruent by SAS criterion.

31.693 Rounded to the nearest Hundredth ​
ioda

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

31.69

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • '9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
  • Since 3 is less than or equal to 4, we would round down.

⸻⸻⸻⸻

31.693 ≈ 31.69

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
