Answer:
x ≈ 52.6°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = = , then
x = ( ) ≈ 52.6° ( to the nearest tenth )
Step-by-step explanation:
step 1. what is the question? maybe the question is what is the value of x in the diagram. okay.
step 2. interior angles of a triangle add up to 180°
step 3. the 3 angles inside the triangle are 10x + 8, 13 + 5x, and (180 - 126)
step 4. (10x + 8) + (13 + 5x) + 54 = 180
step 5. 15x + 21 = 126
step 6. 15x = 105
step 7. x = 7.

Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.
Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements
Total permutation (WITH REPERTITION):
7⁷ = 823 543
