If cos θ = .62 and if 0<θ<90 what is the approximate value of sin θ to the nearest hundredth

Deffense [45]

$\cos\Theta=0.62\\\\\text{Use:}\ \sin^2\alpha+\cos^2\alpha=1\\\\\sin^2\Theta+(0.62)^2=1\\\\\sin^2\Theta+0.3844=1\ \ \ |-0.3844\\\\\sin^2\Theta=0.6156\to\sin\Theta=\pm\sqrt{0.6156}\\\\\sin\Theta_1\approx-0.78\ \vee\ \sin\Theta\approx0.78\\\\\Theta\in(0^o;\ 90^o),\ therefore\ \sin\Theta \ \textgreater \ 0\to\boxed{\sin\Theta\approx0.78}$

What is the answer to > solve 4cos (theta/3) -2 = 0, over [0, 4pi)

Vesna [10]

Hello from MrBillDoesMath!

Answer:

@ = pi/3 (or 60 degrees) or @ = 7 pi/3 (or 420 degrees)

Discussion:

Let "@' denote the angle "theta". We are asked to find @ in the interval [0, 4 pi)

where

4cos(@) - 2 = 0. Adding 2 to both sides

4 cos(@) - 2 +2 = 2 =>

4 cos(@) = 2 Divide both sides by 4

cos(@) = 2/4 = 0.5

This implies that @ = pi/3 (or 60 degrees) or @ = (pi/3 + 2pi) = 7 pi/3 (or 420 degrees)

Thank you,

MrB

Use Euler's Formula to find the missing number.<br>Faces: 20<br>Edges: 30<br>Vertices:

adoni [48]

Answer:

V=12

Step-by-step explanation:

Faces: 20 Edges: 30

Write the Euler's formula for 3-dimensional figures

F+V=E+2

Substitute some variables for their known values

20+V=30+2

Add the numbers on the right side of the equation

20+v=32

Subtract 20 on both sides

20-20+V=32-20

Subtract

V=32-20

Number of Vertices

V=12

Suppose a triangle has 3 sides, 3, 4, 6 which of the following must be true

Inessa [10]

Answer:

B. the triangle in question is not a right triangle

Step-by-step explanation:

A 3-4-5 triangle is a right triangle, so this one, with its longer longest side, is an obtuse triangle. It is not a right triangle.

___

3, 4, 5 is one of the first Pythagorean triples that you learn:

3² + 4² = 5²

These are the side lengths of the smallest right triangle with integer sides. It is worthwhile to remember. This triple is used not only in many math problems (such as this one), but also in real life when it is useful to lay out a right angle.
