HELP MEEEE!!!!!!!!!!!!!!!!
Jlenok [28]

Answer:

19 degrees

Step-by-step explanation:

You know the sum of the interior angles of a triangle is 180 degrees.

So then you can make the equation 82 + 41 + 3x = 180

By solving for x, you get the answer:

123 + 3x = 180

3x = 57

x = 19 degrees

Hope dis helps ya

Select the correct answer.<br> What is the solution to the equation?
Ierofanga [76]

Answer:

B

Step-by-step explanation:

\sqrt{x} + 6 = x ( subtract 6 from both sides )

\sqrt{x} = x - 6 ( square both sides )

x = (x - 6)² ← expand using FOIL

x = x² - 12x + 36 ( subtract x from both sides )

0 = x² - 13x + 36 , that is

x² - 13x + 36 = 0 ← in standard form

(x - 4)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 9 = 0 ⇒ x = 9

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions.

x = 4

left side = \sqrt{4} + 6 = 2 + 6 = 8

right side = x = 4

Since 8 ≠ 4 then x = 4 is an extraneous solution

x = 9

left side = \sqrt{9} + 6 = 3 + 6 = 9

right side = x = 9

Thus the solution is x = 9 → B

Yuri [45]

Answer:

#1. 31.4 square units

Step-by-step explanation:

We are solving for the square units and also we are circumference formular

which is C = R x 2) (3.14)

R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.

Back to the problem

C = R x 2) (3.14)

C =  5 x 2 x 3.14

C = 10 x 3.14

C = 31.4

Can someone tell me how to do this! #2 &amp; #4

2) The area is 1.1 m^2 because to find the area the formula is width*length. SO you would separate it. It would be 0.9 * 1 = 0.9 and 0.4 * 0.5 = 0.2. Then you add it together. So it would be 1.1 m^2. The perimeter is all the sides added together so 4.2 m, but it says mm so you have to convert it and you get 4200.
4) Area is 1.16 cm^2. Again you would seperate it. So, 1 * 1 = 1 and .2 * .8 = .16. Then you add it together and get 1.16 cm^2. The perimeter is all the sides added up. You get 4.2 cm.
