just solve for x
Answer:
31,250 ft²
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the ends of the rectangle will have dimesion (500-x)/2, and the total area will be ...
... A = x(500-x)/2
This function describes a parabola with zeros at x=0 and x=500. The vertex (maximum) will be located halfway between these, at x=250.
The maximum size pen has area ...
... A = 250(500 -250)/2 = 31,250 . . . . sq ft
Answer:
- C. Consecutive interior angles are supplementary
Step-by-step explanation:
Andrew calculated it correctly
Angles 110 and x are supplementary as consecutive interior angles
- 110 + x = 180
- x = 180 - 110
- x = 70
Correct choice is C
Answer:
m∠BOC = 47°
Step-by-step explanation:
m∠AOC = 180 (as it is a straight angle}
m∠AOC = m∠AOB + m∠BOC
m∠AOB + m∠BOC = 180°
3x + 124 +6x + 29 =180
9x + 153 = 180
9x = 180-153
9x = 27
x = 27/9
x = 3
m∠BOC = 6x + 29 = 6*3 + 29 = 18+29 = 47°
Answer:
Step-by-step explanation:
If we are given angles B and C, then all we have to do is add them together and then subtract that from 180 since all the angles of a triangle have to add up to equal 180.
62 + 48 = 110
180 - 110 = 70
Angle A = 70°
