Given 15 cot A = 8, find sin A and sec A.
1 answer:
Answer:
sin A = 15/17
sec A = 17/8
Step-by-step explanation:
15 cot A = 8
First get cot A alone.
cot A = 8 / 15
Since cot is the reciprocal of tan then flip 15 and 8.
tan A = 15 / 8
Now you have the opposite and adjacent sides, just find the hypotenuse with Pythagorean's theorem
15^2 + 8^2 = 289
= 17
Now that you have all the sides use the opposite and hypotenuse to get sine and the adjacent and hypotenuse to get cosine then flip to get secant.
sin A = 15/17
cos A = 8/17
sec A = 17/8

Answer:
c=4×$3.75
Step-by-step explanation:
It would be the problem above because c is the total which equals the total of 4×$3.75.
a^2+b^2=c^2
a^2+24^2=25^2
a^2+576=625
a^2=49
a=7
The answer is 7.
The slope of number 9 equals 0, becuase it is horizontal.
The slope of number 10 equals.
