Answer:
Ans is 59
Step-by-step explanation:
46 +51+y=180 (sum of triangle)
y=180-46-51
y=83
now,
83+x+38=180
x=180-83-38
x=59
value of x is 59
Simplifying
3[x + -1] = 12
Reorder the terms:
3[-1 + x] = 12
[-1 * 3 + x * 3] = 12
[-3 + 3x] = 12
Solving
-3 + 3x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 3x = 12 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = 12 + 3
3x = 12 + 3
Combine like terms: 12 + 3 = 15
3x = 15
Divide each side by '3'.
x = 5
Simplifying
x = 5
⁹P₃=9×8×7=504; ¹⁰C₄=10×9×8×7÷(4×3×2×1)=210.
Equation = (y - 6)/(x - 4) = (5 - 6)/(1 - 4) => (y - 6)/(x - 4) = -1/-3 => 3(y - 6) = x - 4 => 3y - 18 = x - 4 => x - 3y = 14
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
