Answer:
b = 25m
Step-by-step explanation:
Hi there!
We're given angle B and the length of <em>a</em> in this right triangle. We must solve for the length of <em>b</em>. <em>a</em> and <em>b</em> are the two legs of the right triangle.
In this case, we can use the tangent ratio:
Plug in the given information:
Therefore, b = 25m.
We can also use this using special triangle rules. radians is equal to 45 degrees, making this a 45-90-45 triangle. This would make <em>a</em> and <em>b</em> equal in length.
I hope this helps!
Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>- percent
- percentage words problem
- PEMDAS
- population:2500
- decreasing rate:3%
- the population after 11 years
according to the question
population decreases in 1 year
population will decrease in 11 years
- 75×11
- 825
so the population of the town after 11 years will be
2500-825
<h2>1675</h2>
