Answer:
Step-by-step explanation:
In trigonometry, secant in a right triangle, is the reciprocal of the cosine of an angle symbol: sec while cosine is in a right triangle, is the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse.
The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. The cosine of ∠A will be abbreviated as cos ∠A
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
Answer: did you find an answer? I also really need to know
Step-by-step explanation:
The answer is 8r/9
2r = 5s/2 - s/4
2r = 10s/4 - s/4
2r = 9s/4
4 x 2r = 9s/4 x 4
8r = 9s
8r/9 = s
Answer:
<u>120%</u>
<u />
20.4 is 120% of 17.
Step-by-step explanation:
20.4/17 = 1.2
1.2 x 100 = 120%
Hope this helped. Have a good one!
This is how you solve this equation:
y^2-1=48 (add 1 to both sides)
y^2=49 (square root both sides)
y=7 y=-7 (because when you square root, the answer is positive and negative)
Hope this helps!
