Answer:
answer C
Hyperbolic geometry
The sum of the angles of a hyperbolic triangle is less than 180°.
Using: A^2+b^2=c^2
A&b= (√10)^2=10
10+10=c^2
20=c^2
(take the square root of 20)
c=2√5
Your answer is D
Answer: The tree was 27 feet tall
Step-by-step Explanation: First of all Sally was standing 30 feet away from the tree and she looks up at an angle of elevation of 38 degrees to the top of the tree. With this bit of information we can determine that a right angled triangle has been formed with the reference angle as 38 degrees, the side facing it as h (the height of the tree) and the adjacent side as 30. We shall apply the trigonometric ratio as follows;
Tan 38 = opposite/adjacent
Tan 38 = h/30
0.7813 = h/30
0.7813 x 30 = h
23.4 = h
We remember at this point that Sally’s eyes were 4 feet above the ground. What we have just calculated is the height of the tree from “4 feet above the ground” (where her eyes were). Hence the actual height of the tree is calculated as 23.4 plus 4 which gives us 27.4
Therefore the tree was 27 feet tall (approximately to the nearest foot)

Step-by-step explanation:
How much farther than Shamir will Juliet travel in one hour is : b. 3 miles.
<h3>Distance</h3>
1 hour= 60 minutes
Given:
Difference in 10 minutes=1/2 mile
Hence:
Difference in one hour=1/2×(60/10)
Difference in one hour=1/2× 6 mile
Difference in one hour=3 miles
Therefore how much farther than Shamir will Juliet travel in one hour is : b. 3 miles.
