In triangle DEF, the length of DE is √••30 inches, and the length of EF is 3 inches. If it can be determined, what is the length, in inches, of DF ? F. 3 G. √••30 H. √••33 J. √••39 K. Cannot be determined from the given information

The value of DF cannot be determined due to insufficient information. Option D is correct.

Given information:

In triangle DEF, the length of DE is inches, and the length of EF is 3 inches.

It is required to find the length of DF.

Now, the information is insufficient because the type of triangle is not given, and neither the angles are given.

If the triangle is a right triangle, then the third side can be easily found using the Pythagoras theorem. Also, if we know the value of angles, then using the sine or cosine rule, we can calculate the third side.

But based on the given information, the third side cannot be found.

Therefore, the value of DF cannot be determined due to insufficient information. Option D is correct.

K. Cannot be determined from the given information.

Step-by-step explanation:

In the given triangle DEF, DE=√30 Inches, and EF=3 Inches. The length of DF cannot be determined from the given information.

We can only solve for DF if either an angle is given or the type of triangle is specified.

If an angle is given, we can use Sine or Cosine Rule to find the length as appropriate.

If the triangle is a right triangle, we can use Pythagoras Theorem.

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
