The supplement of an angle is \(36^\circ\) less than twice the supplement of the complement of the angle. Find the measure of the supplement. 

And of course, good luck!

Use tan^-1(13/21)

To get tan^-1 use atan 

\(\frac{4}{3}=1\frac{1}{3}=1.\overline{333}\)

All the elements of a set in another set

eight sextillion, seven hundred and eighteen quintillion, sixteen quadrillion, one hundred and seventy-seven trillion

mn - 7m +5n - 9mn + 2n

 Group like terms

       = 1mn -9mn +5n + 2n -7m

       = -8mn +7n -7m

sin( 2A )  =  2 sin( A ) cos( A )

We can find   sin( A )   using the Pythagorean identity.

sin² A  +  cos² A   =   1

sin² A  +  (-4/5)²   =   1

sin² A  +  (16/25)  =   1

sin² A   =   1 - 16/25

sin² A   =   9/25                     Take the square root of both sides.

sin A = 3/5                             Since sin is positive in Quadrant II, we only take the positive root.

Now we can find   sin( 2A )   using the double-angle identity.

sin( 2A )  =  2 sin( A ) cos( A )

sin( 2A )  =  2 (3/5) (-4/5)

sin( 2A )  =  -24/25

Thank you for helping!

Thank you for your assistance!

b² + b - 20

What two numbers add up to  1  and mulitply to  - 20  ?  →  -4  and  +5

-4 + 5 = 1

-4 * 5 = -20

So.....

b² + b - 20    =    (b - 4)(b + 5)

195  *  pi  /  180  =

(13/ 12)  pi      (rads )

if you're finding arc measure of minor arc HJ, 360-281 also equals 79 degrees.

m< HIJ  =  (1/2) ( major arc HJ - minor arc HJ)

101°  =  (1/2) (  281°  - minor arc HJ )    multiply both sides by 2

202°  =  281°  - minor arc HJ          rearrange as

minor arc HJ  =  [ 281 - 202] °  =   79°

arc measure, arc length, or distance apart?

a bit is one-eigth of a byte.

I can't calculate bits and bytes accurately.

explain why you don't understand it.
