Answer:
x = 55
y = 70
Step-by-step explanation:
since it's all sides are equal its an equilateral triangle
each angle of an equilateral triangle is 60°
therefore,
y - 10 = 60 => y = 60 + 10
y = 70
x + 5 = 60 => x = 60 - 5
x = 55

Hey!
Let's solve this together.
5x+1 = 1+x2
Possible Answers: {5,4,3,2}
Lets start with 5.
5(5)+1 = 1+2(5)***
25+1 = 1+10
26 ≠ 11
So, 5 is NOT the answer.
Now, 4.
5(4)+1 = 1+(4)2
20+1 = 1+8
21 ≠ 9
So, 4 is NOT the answer.
Now, 3.
5(3)+1 = 1+(3)2
15+1 = 1+6
16 ≠ 7
So, 3 is NOT the answer.
Lastly, 2.
5(2)+1 = 1+(2)2
10+1 = 1+4
11 ≠ 5
So, 2 is NOT an answer.
So, the answer is: None of the above. None of them can be answers because none of them make the statement true.

Answer:
39°
Step-by-step explanation:
A radius of a circle (segment CD) drawn to the point of tangency (D) intersects the tangent (line DE) at a 90-deg angle.
That makes m<D = 90.
m<D + m<C + m<E = 180
90 + 51 + m<E = 180
m<E = 39
Answer:
The linear inequality would be y ≥ 1/2x - 1
Step-by-step explanation:
In order to find the inequality, first find the equation of the line. To do this, we start by identifying two points on the line. For the purpose of this, we'll use (0, -1) and (2, 0). Now we can use the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (0 - -1)/(2 - 0)
m = 1/2
Now that you have the slope, you can use either point and point-slope formula.
y - y1 = m(x - x1)
y - 0 = 1/2(x - 2)
y = 1/2x - 1
Now that we have this, we look to the shading. If the shading is above, then we make y ≥. If it is under the line, then we make y ≤. In this case, the shading is above. Leaving us with:
y ≥ 1/2x - 1
