Given:
A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.
The pole is 3 feet from the stake.
To find:
The length of the rope to the nearest tenth of a foot.
Solution:
First draw a diagram according to the given information as shown below.
We know that, in a right angled triangle,
In triangle ABC,
Therefore, the length of the rope is 5.2 foot.
Answer:
Step-by-step explanation:
Equation to remember:
where t = time
= 1200 since that's the initial population
= .35 rate of change \\
= 5 years
Plug in the numbers;
Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.
Answer:
D. 20°, 60°, and 100°
Step-by-step explanation:
basically you're testing which set adds up to 180°:
D should immediately catch the eye since it has a simple 100°, and 60+20 is 80, making D the correct answer
a: 189°
b: 90°
c: 120°
d: 180°
Answer:
m=17
Step-by-step explanation:
Complementary means they add to equal 90 degrees.
1) 90-A=36
2)36=2x+2
3) Subtract 2 from both sides, 34=2x
4) Divide by 2 17=x
