In the right triangle below, tanA = 0.45. What is the approximate length of AB?

kodGreya [7K]

Answer with Step-by-step explanation:

We are given that:

tanA = 0.45

tanA= $\dfrac{Perpendicular}{Base}$

= $\dfrac{BC}{AC}$

⇒ $\dfrac{BC}{AC}$ =0.45

⇒ $\dfrac{9}{AC}$ = $\dfrac{45}{100}$

⇒ $\dfrac{9}{AC}$ = $\dfrac{9}{20}$

⇒ AC= 20

Hence, by pythagoras theorem

AB²=AC²+BC²

AB²=20²+9²

AB²=481

⇒ AB=21.9 units

Hence, the approximate length of AB is:

22 units
