Answer:

(1) or A or whatever lol

Step-by-step explanation:

basically just plug the number in, set them equal to each other, and see if the equation is true...

1/2(-2)+3=|-2|

-1+3=2

2=2

1/2(2)+3=|2|

1+3=2

4=2

1/2(3)+3=|3|

1.5+3=3

4.5=3

1/2(-6)+3=|-6|

-3+3=6

0=6

the only one that is a true statement is x=-2

Find the remaining sides and angles. Round your answers to the nearest tenth. Show your work.
zubka84 [21]
Answer: These are all the sides and angles:
a = 3
b = 18.76
c = 19
A = 9.1°
B = 80.9°
C = 90°

Explanation:


As per the usual convention the side c is opposite to the angle C, side a is opposite to angle a, and side b is opposite to angle B.

That means that c is the hypotenuse of the triangle.


Then, a is one leg, and b is the other leg.


Therefore, you can use Pythagorean theorem to find the unknown leg, b:

c² = a² + b² ⇒ b² = c² - a²
⇒ b² = 19² - 3² = 352
⇒ b = √352 = 18.76

Now you can use any trigonometric ratio to find one of the unknowm angles.

I wll use sine ratio to find the angle opposite to a:


sin (A) = a / 19 = 3 / 19 

⇒ A = arcsin (3/19) ≈ 9.1°.

Then, the other angle is: B = 180° - 9.1° - 90° = 80.9°

And those are all the sides and angles:
a = 3
b = 18.76
c = 19
A = 9.1°
B = 80.9°
C = 90°

How to find 60% of 38
finlep [7]

Alright. So we know 60% is .6

And as a fraction it is 3/5. This means 38 x .6 would equal 22.8.

Hope this helps.
