Because cos(x) = 1/sec(x), therefore
cos(48) = 1/1.4945 = 0.6691
The angle 48° is in quadrant 1, therefore cos, sin, tan, sec, csc and cot functions are all positive.
Note that sin(90° - x) = cos(x).
Therefore
sin(90 - 48) = cos(48)
sin(42°) = cos(48°) = 0.6691
Because csc(x) = 1/sin(x), therefore
csc(42°) = 1/sin(42°) = 1/0.6691 = 1.4945
Answer: 1.4945
3,4,5
idk if this is right these could work but what type of triangle and what are you trying to figure out
10^2 + 4 * (6 + 3) - 27 ÷ (9 - 6) = 127
=100 + 4 * 9 - 27 ÷ 3
multiplication & division before addition and subtraction (order of operations rules, PEMDAS)
100 + 36 - 9= 127
136 - 9= 127
127= 127
Place a set of parentheses around (6+3) and (9-6).
Hope this helps! :)
Answer:
B
Step-by-step explanation:
The centre is at the midpoint of the endpoints of the diameter.
Using the midpoint formula, then
centre = (
,
) = (- 1, 1 ) → B
