In triangle abc, cos A= -0.6. Find A and Tan A

Tresset [83]

Answer:

Part 1) $A=126.87^o$

Part 2) $tan(A)=-\frac{4}{3}$

Step-by-step explanation:

we have

$cos(A)=-0.6$

The cos(A) is negative, that means that the angle A in the triangle ABC is an obtuse angle and the value of the sin(A) is positive

The angle A lie on the II Quadrant

step 1

Find the measure of angle A

$cos(A)=-0.6$

using a calculator

$A=cos^{-1}(-0.6)=126.87^o$

step 2

Find the sin(A)

we know that

$sin^2(A)+cos^2(A)=1$

substitute the value of cos(A)

$sin^2(A)+(-0.6)^2=1$

$sin^2(A)=1-0.36$

$sin^2(A)=0.64$

$sin(A)=0.8$

step 3

Find tan(A)

we know that

$tan(A)=\frac{sin(A)}{cos(A)}$

substitute the values

$tan(A)=\frac{0.8}{-0.6}$

Simplify

$tan(A)=-\frac{4}{3}$

Investigators conducting a study regarding the effects of water pollution and peptic ulcer disease obtained the following data:

natima [27]

Answer:

Kindly check explanation

Step-by-step explanation:

The prevalence per 1000 among the exposed :

Total number of diseases among those exposed = 60 + 238 = 298

Prevalence per 1000 among the exposed :

(298 / 9000) * 1000 = 33.11

Prevalence per 1000 among the non exposed :

((90 - 60) + (268 - 238)) / 3000

(60 / 3000) * 1000 = 20

Incidence rate per 1000 among the exposed :

238 / 5940 * 1000

0.0400673 * 1000 = 40.07

Incidence rate per 1000 among the unexposed :

((90 - 30) / (3000-30)) * 1000

(60/2970) * 1000 = 20.2
