Answer: the first part of this question is C, the second part of this question is D
C=90°, A=75°, b=AC=19, x=AB
Without a figure, we see AC is adjacent to angle A, so
cos A = AC/AB = b/x
x = b/cos A = 10 / cos 75° ≈ 38.637
Answer: 38.6
Answer:
A) y=2x-1
Step-by-step explanation:
y-y1 = (x-x1) => y-3 = (x-2) => y-3= 2x-4 => y=2x-1
Y= 2x+10 would be the equation and it would have no solution because there's no value if x nor y
