Answer:
45° bcs
180°-90°=90°
90°:2=45°
Answer:
Step-by-step explanation:
Perimeter of a garden = 2(L+W)
Area of the gerden = LW
L is the length
W is the width
Given
Perimeter = 155ft
Area = 1400ft²
Substitute
1400 = LW
155 = 2L+2W
from 1;
W = 1400/L
Substitute into 2;
155 = 2L + 2(1400/L)
155 = 2L + 2800/L
155L = 2L² + 2800
2L²-155L + 2800 = 0
Factorize
L = 155±√155²-4(2)(2800)/4
L = 155±√24025-22400/4
L = 155±√1625/4
L = L = 155±40.31/4
L = 194.31/4
L = 48.82 feet and;
L = 155-40.31/4
L = 28.67ft
Hence the approximate length of the garden is at least 28.67 feet and at most 48.82 feet.
As go up the number sequence it is just the number added to get the new number plus 1. For example, since 2+3=5, 5+3=8+1=9
Answer:
7/2
Step-by-step explanation:
(3,2) (5,9): Slope -->
(9-2)/(5-3) = 7/2
The answer would be C
2x + 9 = 21
1. 2x = 12
2. x = 6
