Answers:

48°

42°

90°

52°

Answers

Answer 1

Answer:

42

Step-by-step explanation:

from the trigonometric identity

[tex]sin \beta =cos(90 -\beta )[/tex]

if [tex]\beta[/tex]=48 hence

[tex]90-48=42[/tex]

hence

[tex]sin48=cos42[/tex]

Answer:

132°

Step-by-step explanation:

Since there are parallel lines, this will help figure out what the value of x is.

A straight line equals 180°

We know that one side is 48°

Subtract

180 - 48 = 132

Answer:

6.7

Step-by-step explanation:

This is trigonometry. We will have to find the opposite leg and the hypotenuse is given to us as 10. So we will have to use sin.

Soh in Soh cah toa

                  So  sin(42)=x/10

                        10 times sin(42)=x

                             Evaluate using a calculator=6.69130606 and so on

                                 Rounded to the nearest tenth is 6.7

So the answer is 6.7

Answer:

1 1/2

Step-by-step explanation:

1/4 + 1/3 + 11/12

Multiplying the equations to have a common denominator (12).

1/4 times 3 = 3/12

1/3 times 4 = 4/12

3/12 + 4/12 + 11/12

Then add.

18/12

Then convert to mixed fraction.

1 6/12

Then simplify the fraction.

1 1/2

=1×4/4×3+1×4/3×4+11/12

=3/12+4/12+11/12

If you draw a single card once from a deck of ordinary laying cards, what is the probability that it will be a 3 or a black card

Answers

Answer:

The required probability =  0.5385

Step-by-step explanation:

The no. of cards in a deck = 52

The event of having  3 in a draw of a single card = 4/52

The event of having a black card in a draw of a single card = 26/52

The event of having  a black card and 3s = 2/52

Let T represent the event of having  3.

U to represent the event of having  a black card; &

V to represent the event of having  a black card that is 3s

Then the probability that it will be a 3 or a black card is;

P( T or U) = p(T) + p(U) - p(T and U)

P( T or U) = 4/52 + 26/52 - 2/52

P( T or U) = (4+26-2)/52

P( T or U) = 28/52

P( T or U)= 7/13

P( T or U) = 0.5385
