Step-by-step explanation:

The pendulum swings over an angle of 2×(2°30') or 5° so we need to convert this to radian measure first:

$5° × \left(\dfrac{\pi}{180°}\right) = 0.0873\:\text{rad}$

so the arc length is given by

$s = r\theta = (50\:\text{cm})(0.0873\:\text{rad}) = 4.36\:\text{cm}$

Answer:

$\sqrt[8]x = x^\frac{1}{6}$

Step-by-step explanation:

Given:

$\sqrt[6] x$

Required

Represent as an exponent

In indices, we have:

$\sqrt[n]x = x^\frac{1}{n}$

By comparison:

$\sqrt[8]x = \sqrt[n]x$

$n = 8$

Apply this law to the given expression:

We have:

$\sqrt[8]x = x^\frac{1}{6}$

---------------------------------------------
Formula
---------------------------------------------
Sum of all exterior numbers = 360°

---------------------------------------------
Apply Formula
---------------------------------------------
z + 45 + 55 + 78 + 74 + z = 360

---------------------------------------------
Combine likes term
---------------------------------------------
2z + 252 = 360

---------------------------------------------
Take away 252 from both sides
---------------------------------------------
2z = 360 - 252
2z = 108

---------------------------------------------
Divide by 2 on both sides
---------------------------------------------
2z = 108
z = 108 ÷ 2
z = 54

---------------------------------------------
Find z + 45
---------------------------------------------
z + 45 = 54 + 45
z + 45 = 99°

---------------------------------------------
Answer: 99°
