If the tangent of an acute angle is 1/4, what is the cosine of that angle?
ozzi

Answer:

0.97

Step-by-step explanation:

It is known that the tangent of an angle is given by the quotient between its sine and its cosine.

tan(x)=\frac{sin(x)}{cos(x)} =\frac{1}{4} \\\frac{1}{4}cos(x)=sin(x)\\

Applying the following property:

sin^2(x) +cos^2(x) = 1\\(\frac{1}{4}cos(x))^2 +cos^2(x) = 1\\\\\frac{17}{16}cos^2(x) = 1 \\cos(x)=0.97

The cosine of that angle is 0.97.

Definition

Having integrity means doing the right thing in a reliable way. It's a personality trait that we admire, since it means a person has a moral compass that doesn't waver. It literally means having "wholeness" of character, just as an integer is a "whole number" with no fractions.

So the asnwer is

-5 < -1

ira [324]

Answer:

option A: 0.2357

Step-by-step explanation:

P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39)

P(X < 1.76) = 0.0126 (as per the excel output)

P(X < 2.39) = 0.7769

Hence P( X> 2.39) = 1- 0.7769 = 0.223

P( less than 1.76 or greater than 2.39) = P(X < 1.76) + P( X > 2.39) = 0.0126 + 0.223 = 0.2357

P( less than 1.76 or greater than 2.39) = 0.2357
