Answer:
Step-by-step explanation:
Quidnet Beach in Massachusetts offers fantastic views of Sankaty Head Light, a lighthouse that overlooks the Atlantic Ocean.
You need to isolate the "x" in both inequalities
5x + 7 ≤ -3 Subtract 7 on both sides
5x ≤ -10 Divide 5 on both sides
x ≤ -2
3x - 4 ≥ 11 Add 4 on both sides
3x ≥ 15 Divide 3 on both sides
x ≥ 5
This is your simplified inequalities:
5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A
To find x:
use the formula: tan° = opposite/adjacent
tan 61° = x/10
answer: 18.0
other length:
use the formula: cos° = adjacent/hypo
cos 61° = 10/y
answer: 20.6
The 2-ft wide wall on each side adds a total of 4-ft to the each size of the land dimensions making it 20-ft-by-24-ft land now.
Perimeter is calculated as an addition of all sides so 20+20+24+24 = 88-ft perimeter assuming it is a rectangle land shape.
I believe it would be 122 degrees.
360-116=244
since the two sides are congruent, divide 244 by 2 to find the remaining angles, which would be 122
