Answer:

Step-by-step explanation:
Given:
Angle of elevation = 70°
Length of string = 68 m
We need to find the height of the kite.
Solution:
Requirement figure attached in file.
Where:
BC = 68 m
AC = h (Height of the kite)
∠ABC = 70°
Using Cosine rule to find the height of the kite.



Therefore, height of the kite from Brian's head

Answer:
2x-12+5=3x-3
1. subtract 3x-2x
-12+5=x-3
2.-12 add to 5
-7=x-3
3. add three to seven
-4=x
Step-by-step explanation:
Answer:
x is 11 degree
Step-by-step explanation:
35+5x=90
5x=90-35
5x=55
x=11
this answer is found by linear equation method
Step-by-step explanation:
It is given that, Katie walks 2 ft forward and 5 ft backwards. We need to find her displacement traveled.
The difference between final position and the initial position is equal to displacement. It is the shorted path covered.
Let forward is +x and backward is -x
Initial position of Katie = +2 ft
Final position of Katie = -5 ft
Displacement = final position - initial position
= -5 - 2
Displacement = -7 ft
So, her displacement is 7 feet in backward direction.
Answer: It decreases
Step-by-step explanation:
Theoretically, let's say n = 15
15 + 15 = 30
Now, let's use 14, because 14<15
14 + 15 = 29
So, the value decreases as n decreases
