Answer:
The triangle has one solution. The remaining side c ≈ 4 and remaining angles B = 30°; C = 31°.
Option D is correct.
Step-by-step explanation:
if angle A is obtuse and if a > b then the triangle has one solution
We are given ∠ = 119° which is obtuse and side a= 7 and side b - 4 i.e 7>4 so, the triangle has one solution.
Finding remaining side c and ∠B and ∠C
Using Law of sines to find ∠B
a/sin A = b/sin B
7/sin 119° = 4/sin B
7 * sin B = 4 * sin 119
7*sin B = 4(0.874)
sin B = 3.496/7
B = sin^-1(0.4994)
B = 29.96 = 30°
We know that sum of angles of triangle = 180°
So, 180° = 119° + 30° +∠C
180° = 149° + ∠C
=> ∠C = 180° - 149°
∠C = 31°
Now finding c
b/sin B = c /sin C
4/Sin 30 = c/sin 31
4* sin 31 = c*sin 30
4*0.515 = c* 0.5
=> c = 4*0.515/0.5
c = 4.12 ≈ 4
So, Option D one solution; c ≈ 4; B = 30°; C = 31° is correct.

Answer:
Option C) 4 cubic inches is the volume of the rectangular prism.
Step-by-step explanation:
It is given that, 108 cubes with an edge length of 1/3 inch are needed to fill a rectangular prism.
Therefore, the volume of the rectangular prism is equal to the volume of the 108 cubes needed to fill that rectangular prism.
So, we need to find out the volume of those 108 cubes in order to find the volume of the rectangular prism.
The formula for finding the volume of a cube is given by,
Volume of a cube = a³
where a represents the edge length
We know that, the edge length is 1/3 inch.
⇒ a = 1/3
Volume of a cube = (1/3)³
⇒ 1/3 × 1/3 × 1/3
⇒ 1/27 cubic inches
To find the volume of 108 cubes :
⇒ 108 × volume of one cube
⇒ 108 × 1/27
⇒ 4 cubic inches.
∴ The volume of 108 cubes is the volume of rectangular prism which is 4 cubic inches (option C)
