Step-by-step explanation:
z = 180 - (180 - 114.8) - 45.6 = 114.8-45.6 = 69.2°
Answer: D. line d
Step-by-step explanation:
Answer: D. line d
A function is general describe as y = mx + b, so we need to set this function in y form.
2x + 5y = -10
5y = - 2x - 10 (Subtract 2x from both side, to make sure there are only y value in the left side)
y = - 2/5x -10/5 (Divide by 5 from both side)
y = -2/5x - 2 (Simplified)
-2/5x was the <em>m</em> or the slope, it shows how the line was change. -2/5x is negegative, which means is decreasing, and going downward, only line b and d fits.
-2 is the y-intercept, where y is equal to 0, (-2,0)
The y-intercept for line b is (2,0), so it can't be. Thus, the y-intercept for line d is (-2,0), so it fit.
The equation of the line in point-slope form is y = -1/3 x + 20/3 and 3y + x = 20
<h3>Equation of a line</h3>
The equation of line perpendicular to another line in point slope form is expressed as;
y-y₁ = -1/m(x-x₁)
Given the equation of a line x -3y - 8 = 0
x - 3y = 8
-3y = -x + 8
y = 1/3x - 8/3
Slope m = 1/3
Substitute the point (-7, 9) and slope 1/3 into the equation
y-9 = -1/3(x-(-7))
y-9 = -1/3(x+7)
3(y-9) = -(x+7)
3y-27 = -x -7
3y = -x + 20
y = -1/3 x + 20/3
Write in general form.
3y = -x + 20
3y + x = 20
Hence the equation of the line in point-slope form is y = -1/3 x + 20/3 and 3y + x = 20

Getting rid of the fraction will make the rest of the equation easier to solve.
→ A = (1/2)bh
→ 2 × A = 2 × (1/2)bh
⇒ 2A = bh
To solve for b, divide both sides by h:
2A/h = b
So, b = (2A)/h.
Hope this helps!
