Answer:
<u>Option D. 53.1°</u>
Step-by-step explanation:
The rest of question is as shown in the attached figure.
It is required to find the measure of angle S
Given that : r = 12 and t = 20
We should know that : cos (∠S) = Adjacent/Hypotenuse
∴ cos (∠S) = r/t = 12/20
use the inverse cosine function.
∴S = arc-cos (12/20) ≈ 53.1°
<u>The correct answer is option D. 53.1°</u>
2/ 17 because it’s 17 marbles and I hav a 2/17 chance of pulling 2 yellows
Answer:
C
Step-by-step explanation:
Given
5x + 7 ≤ - 3 or 3x - 4 ≥ 11
Solve the inequalities either side of the or
5x + 7 ≤ - 3 ( subtract 7 from both sides )
5x ≤ - 10 ( divide both sides by 5 )
x ≤ - 2
or
3x - 4 ≥ 11 ( add 4 to both sides )
3x ≥ 15 ( divide both sides by 3 )
x ≥ 5
Solution is x ≤ - 2 or x ≥ 5 → C
