If each interior angle of a regular polygon measures 168 how many sides does the polygon have

lbvjy [14]

Answer:

If the interior angle is 168, then the exterior angle is 180 - 168, or 12. The 360 degrees is evenly distributed over all of the angles, so 360/12 = 30 sides. The formula for the sum of the angles in an n-sided polygon (in degrees) is 180(n-2).

The average of 5 numbers is 85 . If 3 of the numbers are 102,96 and 80 respectively, what is the sum of the other 2 numbers ?

Vadim26 [7]

Answer:

147

Step-by-step explanation:

Multiply the average by the number of values

85*5=425

Find the sum of the 3 values you have

102+96+80=278

Take the sum of the 3 values you have away from the sum of all 5 values

425-278=147

What does it mean to use the cosine value of an inverse of tan θ?

Bond [772]

Answer:

$\boxed{ \begin{array}{ccc} \displaystyle \theta = {120}^{ \circ} \\ \displaystyle\sin( {120}^{ \circ} ) = \frac{ \sqrt{3} }{2} \end{array}}$

Step-by-step explanation:

we are given a inverse trig

we want to figure out the value of $\theta$

in that case we can consider using unit circle in unit circle the value of arctan (-√3)=120°

therefore,

the value of theta is 120°

likewise by unit circle the value of sine is

$\displaystyle \sin( {120}^{ \circ} ) = \frac{ \sqrt{3} }{2}$
