tan(x) = 10/60

tan(x) = 1/6

tan(x) = a -> x = arctan(a) + πn

x = arctan(1/6) + πn

x = 0.165 + πn

Best of Luck!

Find the square of the following without actual multpliation .<br><br> 43

devlian [24]

I'll explain how I found it without actual multiplication,

${40}^{2} = 1600 \\ {3}^{2} = 9 \\ 2 \times 40 \times 3 = 240 \\$

So,

${43}^{2} = 1600 + 240 + 9 \\ = 1849$

Hope this will help....

Solve for the value of n.

frosja888 [35]

Answer:

n= 27

Step-by-step explanation:

To solve first subtract the 90-degree angle:

180-90= 90

Then, convert into an equation:

3n+9= 90

Subtract 9 from both sides:

3n=81

Then divide by 3:

n= 27

Hope this helps!
