Use trigonometry

we are given opposite(27) and hypotenuse(28), so use sin

sin=opp/hyp

sin(x)=27/28

x=arcsin(27/28)

x=74.64111442

The ratio of the measures of all three angles in a triangle is 14:5:11. Find the measures of the angles.

Maru [420]

Answer:

30, 66 and 84 degrees.

Step-by-step explanation:

The number of degrees in a triangle is 180 degrees.

Work out the 'multiplier':

It = 180 / (14+5+11)

= 180/30

= 6.

So the angles are:

14*6 = 84

5*6 = 30

11*6 = 66.

Darren has the option of investing in either Stock A or Stock B. The probability of the return of Stock A being 25% is 0.45, 14%

Lunna [17]

Answer:

C)A is 15.95% ,B is 11.85%

Step-by-step explanation:

We know that the expected value in probability distribution is given as

Lets X is the expected value then

$X= \sum_{i=1}^{i=n} X_i P_i$

For stock A

X=0.25 x 0.45+0.14 x 0.25+0.04 x 0.3

X=0.1595

So the expected return for A is 15.95%

For stock 9

X=0.3 x 0.3+0.09 x 0.25+0.02 x 0.3

X=0.1185

So the expected return for B is 11.85%

So our option C will be the answer of that problem.
