✔cos^2A+sin^2A=1
✔1-cos^2A=sin^2A
✔cos2A=cos^2A-sin^2A
✔sin2A=2.sinA.cosA
secA=1/cosA
tgA=sinA/cosA
sin^2A/1/cos^2A-sin^2A/cos^2A
sin^2A.cos^2A/cos2A
2.sin^2A.cos^2A/cos2A
sin2A.2.sin2A/cos2A
tg2A.2.sin2A
Answer:
13 car lengths
Step-by-step explanation:
65 (1/10) = 6.5
6.5 (2) = 13
Answer:

Step-by-step explanation:
First, you need to get the equation into y = mx + b form, like this:
Add y to both sides to get y + 2x − 5= 0
Then subtract 2x to get y - 5 = -2x
Add 5 to get y = -2x + 5
Now we know the slope is -2, or -2/1.
A line that is perpendicular to it has a slope that is the first line's slope's opposite reciprocal. This means flip the fraction upside down and change the sign, which gives you positive 1/2.
