Answer:
41
Step-by-step explanation:
BDA = DBC+CBA
84=5x+3 + 6x-7
Combine like terms
84 = 11x-4
Add 4 to each side
84+4= 11x -4+4
88 =11x
Divide each side by 11
88/11 = 11x/11
8 = x
We want angle ABC
ABC = 6x-7
=6*8 -7
=48-7
=41
Step 1: Add up all the scores.
Step 2: count the number of scores.
step 3: divide the sum of the scores by the number of scores themselves.
step 4: The answer is 26 points.
We know that
in a right triangle
cos θ=adjacent side angle <span>θ/hypotenuse
in this problem
</span>adjacent side angle θ=38 in
hypotenuse=40 in
cos θ=38/40
θ=arc cos (38/40)-------> 18.19°-------> 18°
the answer is
18 degrees
Answer:
About 113,097.34 units
Step-by-step explanation:
The volume of a sphere can be found with the equation V = 
πr³ when r is the radius.
V = πr³
V = π(30)³
V ≈ 113,097.34 units
