Answer:
<h2>y = 1</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point on a line</em>
We have <em>m = 0, (3, 1) → x₁ = 3, y₁ = 1</em>.
Substitute:
<em>add 1 to both sides</em>
Other method.
If the slope is equal 0, then it's a horizontal line.
The equation of a horizontal line: <em>y = a</em>.
We have the point on a line (3, 1) → x = 3, y = 1.
Therefore the equation is <em>y = 1</em>.
Remark: What might be confusing you is the the given expression must add up to 90o. You know this because <B = 90 so the other two angles must be 90o.
Equation
5x - 10 + 6x - 21 = 90 Combine like terms on the left
11x - 31 = 90 Add 31 to both sides.
11x - 31 + 31 = 90 + 31
11x = 121 Divide by 11
x = 121/11 = 11.
Find the value of 6x - 21
6*11 - 21 = 66 - 21= 45
Comment
The central angle for arc AB (which is double ADB = 2*45 =90) is 90. So arc AB = 90

Answer:
19329, you are correct
Step-by-step explanation:
Volume = 
Volume = 
Volume= 19329.84
not rounded= 19329
Image is very dark. I guess you are asking the value of x. If so:
The mentioned angle is aright angle that is divided into 2 smaller angles, one of 69° and the other of (2x°-1). Hence
69° + 2x°- 1° = 90°
2x° = 90° + 1° - 69°
2x° = 22°
And x = 11°
If x = 11,then 2x - 1 = 21° (missing angle)
