Answer:
Step-by-step explanation:
<u>Use midpoint formula</u>
- x = (x₁ + x₂)/2
- y = (y₁ + y₂)/2
#3
Endpoints (0, 0) and (6, 8)
<u>Midpoint has coordinates:</u>
Correct choice is C
#4
Endpoints (-5, 3) and (3, 15)
<u>Midpoint has coordinates:</u>
- x = (-5 + 3)/2 = -1, y = (3 + 15)/2 = 9
- Point is (-1, 9)
Correct choice is B

Answer:
Step-by-step explanation:
sec (-x)-sin (-x) tan (-x)=cos x
sec(x)-(-sin x)(-tan x)=cos x
1/cos x-sin x(sin x/cos x)=cos x
multiply by cos x
1-sin ²x=cos²x
or 1=sin²x+cos²x
which is true.
Since the wires are going to make an X, if one angle is 72 deg, then you know the angle directly opposite to it is also 72 deg. Looking at a single side of the x, you see there is a total 180 deg angle (72 + unknown angle), so the unknown angle is 180 - 72, and the angle directly opposite to it will be the same.
