12) Find mZVUT if mZVUT = 10x +9,<br> m_BUT = 7x - 1, and mZVUB= 37º.

Mariulka [41]

Answer:

99°

Step-by-step explanation:

m∠VUT = 10x + 9
m∠BUT = 7x - 1
m∠VUB = 37°
m∠VUT = ?

m∠VUT = m∠BUT + m∠VUT
10x + 9 = 7x - 1 + 37
10x - 7x = 36 - 9
3x = 27
x = 9

<u>Angle VUT measures:</u>

10x + 9 = 10*9 + 9 = 99°

A circle has a radius of 5.4 m. what is the exact length of an arc formed by a central angle measuring 60°? enter your answer in

velikii [3]

The length of the arc of the circle with a radius of 5.4 m and the central angle measuring 60° is 5.655 meters.

<h3>What is the Length of an Arc?</h3>

The length of an arc is given by the formula,

$\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360}$

where

θ is the angle, which arc creates at the centre of the circle in degree.

The length of the arc of the circle with a radius of 5.4 m and the central angle measuring 60° can be written as

$\text{Length of the Arc} = 2\pi r \dfrac{\theta}{360}$

$= 2 \times \pi \times 5.4 \times \dfrac{60}{360}\\\\=5.655\rm\ m$

Hence, the length of the arc of the circle with a radius of 5.4 m and the central angle measuring 60° is 5.655 meters.
