If tan 0=3/4 find sin0

Mathematics
1 answer:
bija089 [108]3 years ago
6 0

Answer:

sin O = \frac{3}{5}

Step-by-step explanation:

given tan O = \frac{3}{4} = \frac{opposite}{adjacent}

Then this is a right triangle with legs 3 and 4

Using Pythagoras' identity then the hypotenuse (h ) is

h = \sqrt{3^2+4^2} = \sqrt{25} = 5, hence

sin O = \frac{opposite}{hypotenuse} = \frac{3}{5}

At a carnival, food tickets cost $2 each and ride tickets cost $3 each. A total of $1,240 was collected at the carnival. The num
horrorfan [7]

in the equation as we can say x= 2y-10.

so, substitute x=2y-10 everywhere then the x in 1240 gets cancelled with 2y-10 then solve the remaining you will get 4y-20+3y=1240

7y=1260

y=1260/7

y=180

then substitute the value of y everywhere

2x+3y=1240

2x+3(180)=1240

2x=1240-540

2x=700

x=350

DONE.

if two dice are thrown together , what is the probability of getting an even number on one die and odd number on the other die ?
Veronika [31]

Answer:

1/2

Step-by-step explanation:

the probability of the die rolling an even number  =  the probability of the die rolling an odd number  =1/2

Let us name these  2  dice as  A  and  B

One die can roll an even and the other can roll an odd, in the following cases

A  rolls even and  B  rolls odd. The probability of this happening  =1/2×1/2

A  rolls odd and  B  rolls even. The probability of this happening  =1/2×1/2

∴  The required probability

=1/2×1/2+1/2×1/2

=1/4+1/4

=1/2
