For this, you use the Law of Distribution and multiply -1 by all terms in the parentheses. 7 • -1 = -7; -c • -1 = c. Then you combine them, but since c is a variable, -7 + c is the most simplified it can get. I hope this helped!

For the triangle above, find sin A. a. 36° c. 0.9323 b. 50° d. 0.385
Lerok [7]
The picture in the attached figure

we know that
in the right triangle ABC
sin A=opposite side angle A/hypotenuse

in this problem
opposite side angle A=BC-----> 10
hypotenuse=AB-----> 26
so
sin A=10/36------> sin A=0.3846------> sin A=0.385

the answer is
the option <span>d. 0.385</span>

There is a bag of marbles with 7 blue marbles, 7 yellow marbles, and 7 red marbles. You are going to choose one marble at random
arsen [322]

(Since there are no options to chose from, I guess I'll just do my own answer and you'll have to pick the closest one to this one. Or, you could comment the options and I could help you there too.)

Answer:

Yes, the outcomes are likely because there is an equal number of each type of marble.

Step-by-step explanation:

Since there is an equal number of each color of marble, the outcomes of the event are equally likely. If there were more of one marble, it would be unlikely.

For example, if there were 7 blue marbles, 7 red marbles, but there were 8 yellow marbles, then the event would be unequally likely because there were more of the yellow marbles.  So the answer is yes, the outcomes are equally likely.

It would be FANTABULOUS if I could get BRAINLIEST!!!!!!!

Have a great day!! ;p

If the sizes of the angle of a triangle are 3x, 5x , and 4x , find the smallest anhge of the traingle
ludmilkaskok [199]

Answer:

45

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

3x+5x+4x = 180

Combine like terms

12x = 180

Divide by 12

12x/12 =180/12

x = 15

The smallest angle is 3x

3(15) = 45
