Answer:
[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10

Review the graph of the function f(x).
On a coordinate plane, a curve starts at closed circle (1, negative 2) and curves up through (0, 1) to (negative 5, 2).
The function shown has an endpoint discontinuity. Which statement describes the one-sided limits at the discontinuity?
Answer:
b
Step-by-step explanation:
edg 2020
'Function' is described as 'a relation in which each component of the domain is related to precisely one component of the codomain.'
B). The statement second "Limit of f(x) = - 2 as x approaches 1 minus. Limit of f(x) DNE as x approaches 1+" correctly elaborates the single-sided limits when the end-point dislocates.
'End-point discontinuity' is described as a function that carries a shut endpoint at its interlude.While 'one-sided limits' are described as the limit(any out of the two) belonging to a function (x) when x advances towards either side(left or right). Thus, it limits x and the rest values remain the same. In the given function, the one-sided limit of the function(x) equals to -2 when it advances towards -1 and DNE when it advances towards 1+.Thus, option B is the correct answer.

this is area right???
Answer:
Yes
Step-by-step explanation:
So permiter is two*lengths plus 2*width of a shape.
Area is the length times the width.
For examplel if a square has a length of 2, and a width of 3 the permiteter is:
2*2+3*3=
4+9
=
13
On the other hand, area would be:
2*3

I need help with this and also the explanation plz
Answer:
The correct answer is 0 or A
Step-by-step explanation:
2/0+2 + 1/5 = 6/0+5
2/2 + 1/5 = 6/5
1 + 1/5 = 6/5
5/5 + 1/5 = 6/5
6/5 = 6/5

5 (x + 8) = -10 what's the answer
Answer:
x = - 10
Step-by-step explanation:
5(x + 8) = - 10
5x + 40 = - 10
5x + 40 - 40 = - 10 - 40
5x = - 50
5x ÷ 5 = - 50 ÷ 5
x = - 10

Solve for x and explain how you got your answer please
-3x -5 = 16
Answer:
x = -7
Step-by-step explanation:
-3x -5 = 16
step 1 add 5 to each side
-5 + 5 cancels out
16 + 5 = 21
we now have -3x = 21
step 2 divide both sides by -3
-3x / -3 = x
21 / - 3 = -7
we're left with x = -7
Answer:
x = -7
Step-by-step explanation:
-3x -5 = 16
+5 +5
-3x = 21
-3x/-3 = 21/-3
x = -7
