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!
