Let abc be a right triangle with mlc = 90°. given tan la =0.5, find tan lb.

  tan(∠B) = 2

Step-by-step explanation:

In a right triangle, the relationships of the tangents of the acute angles is ...

  tan(∠B) = cot(∠A) = 1/tan(∠A)

For tan(∠A) = 0.5, this means ...

  tan(∠B) = 1/0.5 = 2

the answer will be the last one

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
