Answer: D) csc (2π/3)
<u>Step-by-step explanation:</u>
2π/3 is in Quadrant II
Quadrant II has a negative x-value and a positive y-value.
x-values are: cos & sec
y-values are: sin & csc
tan = y/x so will be negative in Quadrant II
A) sec = -
B) tan = -
C) cos = -
D) csc = + this works!
Answer: 24 model airplanes can be made in 2 hours.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Slope of the line is determined by
The rise can be calculated by taking the y coordinates of 2 points and subtracting them.
The run can be calculated by taking the x coordinates of 2 points and subtracting them.
so
slope =
Answer: b=11.26
Step-by-step explanation:
using the length 15 solve for the lengths z and x because the big triangle is also a 30 60 90. x=7.5, z=12.99 (13). Once you know z you can solve for y and b. y=6.5 and b=11.26.
