The measure of angle x will be 88 degrees. Then the correct option is C.
The complete question is attached below.
<h3>What is law of cosine?</h3>
Let there is a triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:
2ab cos θ = a² + b² – c²
The triangle is shown below.
Then the value of the variable x will be
2 · 7 · 10 · cos x = 7² + 10² – 12²
140 · cos x = 49 + 100 – 144
cos x = (149 – 144) / 140
x = 87.95 ≈ 88°
Then the correct option is C.

Answer:
B. 523.33 cubic units
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
V = 4/3 (3.14) 5^3
V =523.3333333
V = 523.33 units^3
Answer:
(fog)(x) = x^2
Step-by-step explanation:
Here g(x) = x^2 + 14 becomes the input to f(x):
(fog)(x) = [x^2 + 14] - 14
(fog)(x) = x^2 (answer)
