sin(0) = opposite/hypotenuse = 2/5
cos(0) = adjacent/hypotenuse = sqrt21/5
tan(0) = opposite/adjacent = 2/sqrt21 * sqrt21/sqrt21 = 2sqrt21/21
cot(0) = adjacent/opposite = sqrt21/2
sec(0) = hypotenuse/adjacent = 5sqrt21/21
Answer:
Step-by-step explanation:
22 - 2k = -4k - 16
22 + 2k = -16
2k = -38
k = -19
1274 divided by 14 equals 91, see attachment below
Answer: y = 1/2x + -1/2z
Explanation: first, add -x to both sides
x-2y + -x = z + -x
-2y = -x+z
Then, divisive both sides by -2
-2y/2 = -x+ 2/-3
y = 1/2x + -1/2z
The answer is 8,000+100+20+8
