Answer:

20 degrees

Step-by-step explanation:

I don't know why the 30 degrees was given at point A because you don't need that.

The equation is;

Sinx=  Opposite/Hypotneuse

     x = Sin inverse (50/146)

        = 20.02

        Rounded to 20 degrees

Given the measures a = 10, b = 40, and A = 30°, how many triangles can possibly be formed?
arlik [135]

Answer:

no triangle can be formed with the given values (i.e 0 triangle).

Step-by-step explanation:

Given;

length of side a, = 10

length of side b, = 40

angle A, = 30°

Apply sine rule to determine the angle of the second side (B);

\frac{sin \ A}{a} = \frac{sin \ B}{b} \\\\\frac{sin \ 30^0}{10} = \frac{sin \ B}{40}\\\\sin \ B = 40(\frac{0.5}{10} )\\\\sin \ B = 2

The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.

Geometry<br> What is the value of x to the nearest tenth?
Setler [38]

Answer:

  x = 9.4

Step-by-step explanation:

The angle bisector divides the sides proportionally:

  x/15.4 = 4.7/7.7

  x = (15.4)(4.7/7.7) . . . . multiply by 15.4

  x = 9.4
