Answer:
x = +√30
Step-by-step explanation:
Please write 30 = x squared as 30 = x^2.
If x^2 = 30, there are two solutions: x = +√30 and x = -√30.
Several possible answers are given. x=30−−√ is closest to the correct one, but must be written as x = √30. Please ask someone how to find the "√" operator in Brainly. Or, just write "sqrt( )" instead.
Answer:

Step-by-step explanation:
we know that
An <u><em>equilateral triangle</em></u> has three equal sides and three equal interior angles (each interior angle measure 60 degrees)
so
The perimeter is equal to

where
b is the length side of the equilateral triangle
we have

substitute

solve for b

Find the area
The formula of area applying the law of sines is equal to

substitute the value of b




<h2>The area A of a triangle is given by the formula A=1/2*b*h where b is the base and h is the height of the triangle.</h2>

Answer:
x < -4
Step-by-step explanation:
Hello!
I don't see the drop-down menus, but I will try to help as best as I can...
Like any other equation, you are trying to get x by itself.
Our first step will be to subtract 13 from both sides.
-7x + 13 > 41
-7x > 28
Now, we will need to divide -7 from both sides. But, remember, dividing or multiplying a negative number will switch, or flip, the sign.
-7x/-7 > 28/-7
Doing the above equation will provide us with x all alone on one side:
x < -4
Hope I helped!

Answer:
25
Step-by-step explanation:
so 180-50=130 so we have x and 130 now umm uuu o ok so the parellel lines it makes it to where there is gonna be 2 xs in the triangle so 180-130=50 50 divided by 2=25 so x = 25
