Please help! number 18
1 answer:
Knowing that a straight line is 180° you can use this to your advantage. If you take all parts of the ratio and add them together you can get the total number of "pieces" the 180° will be divided into.
Then divide the 180° by the total.
Now you can use the value for one "piece" and multiply it by how ever many the ratio says.
The angle FOG has the 4 value of the ratio so you multiply 20 by 4 to get the value of the angle.
m<FOG = 80°
Then divide the 180° by the total.
Now you can use the value for one "piece" and multiply it by how ever many the ratio says.
The angle FOG has the 4 value of the ratio so you multiply 20 by 4 to get the value of the angle.
m<FOG = 80°

Answer:
Area of the rectangular Field = 3 8/9 km²
Step-by-step explanation:
Length of the field = 2 1/3 km
Width of the field = 1 2/3 km
Area of a rectangular Field = length × width
= 2 1/3 × 1 2/3
= 7/3 × 5/3
= (7*5)/(3*3)
= 35/9
Area of the rectangular Field = 3 8/9 km²
Perimeter of the rectangular Field = 2(length + width)
= 2(2 1/3 + 1 2/3)
= 2(7/3 + 5/3)
= 2(7+5/3)
= 2(12/3)
=2(4)
= 8 km
Perimeter of the rectangular Field = 8 km
your answer will be (x+3)(x+4)
