The tangent half angle formula, one of several, is
We have θ is opposite 4 in the 3/4/5 right triangle so
Answer: 1/2
This is actually pretty deep. It says half the big acute angle in the 3/4/5 triangle is the small diagonal angle of the 1x2 rectangle. Similarly, the small acute angle in 3/4/5 triangle is twice the small diagonal angle of the 1x3 rectangle.
Answer:
6<em>i</em> and -6<em>i</em>
Step-by-step explanation:
since its a negative then you have to remember to add a i
Answer:
(A)
Step-by-step explanation:
Let y be the length of the rectangular backyard and then according to the question, y should be atleast 150 ft, then the possible inequality is:
and the distance around should be no more than 450ft, then the possible inequality is:
Then, the shaded region (green) is the possible dimensions of the backyard.
2x=16
X=8
Make sure to do step by step and double check by plugging the answer in.
It would be: 5.5 * 10⁵ * 23000
= 5.5 * 10⁵ * 2.3 * 10⁴
= 12.65 * 10⁹
= 1.265 * 10¹⁰
In short, Your Answer would be Option B
Hope this helps!
