<span>Since the paddock assumes a rectangular shape the area is 1/2 * b * h.
From Pythagorean AB^2 = BC^2 + AC^2
(3)^2 = (x + 0.4)^2 + x^2
9 = x^2 + 0.8x + 0.16 + x^2
So 2x^2 + 0.8x + 0.16 - 9 = 0
2x^2 +0.8x- 8.84 = 0
Using the quadratic formula
The solutions are 1.911 and -2.31
The area therefore is
area=1/2 * b * h
=1.91*2.31/2 = 2.21km²
1hectare = 0.01km²
2.21km^2 = 221ha</span>
To be honest. That’s a hard question there
Answer:
x = 13
Step-by-step explanation:
Since AD is a straight line, then the 3 angles at C sum to 180° , thus
∠ BCE = 180° - (90 + 64)° = 180° - 154° = 26°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ABE is an exterior angle of the triangle, thus
3x = x + 26 ( subtract x from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
Here... we're dividing first to find out how much he makes per hour. 313.25 divided by 35 so he makes $8.95 per hour. now divide 366.95 by 8.95 to find out how many hours he worked this week, so this week he worked 41 hours this week.
