The first one and A and the second one is c
Answer:
1. sine = opposite / hypotenuse = 30 / 34 = 15 / 17
cosine = adjacent / hypotenuse = 16 / 34 = 8 / 17
tangent = opposite / adjacent = 30 / 16 = 15 / 8
2. you have to use the law of sines function
the formula for law of sines is
sin of angle A / side A = sin of angle B / side B = sine of angle C / side C
The information we know is sin of a and side a which is 90 degrees and side A length of 20
we don't know Side B and C
we know sin of angle B = 45 degrees
all we have to do is ratios
now divide both sides by sin(90
left side both cancel and on right side 14.14/ sin(90 = 14.14 is the answer
Step-by-step explanation:
Answer: A
<u>Step-by-step explanation:</u>
Create a table for y = x when x ≤ -1 and y = -x when x > 1.
Then, compare the coordinates from the table to the graph. The first graph, <em>which I consider to be graph A</em>, matches the coordinates from the table.
Answer:
(x-4)(x-2)
Step-by-step explanation:
Find two numbers that multiply to 8 and add to -6
15s=2550
(divide both sides by 15)
