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

garik1379 [7]

In the right triangle ABC wherein AB is the hypotenuse, BC is the opposite and CA is the adjacent tanA=0.45. The approximate length of AB which is the hypotenuse is 22, Opposite (BC) is 9 and Adjacent (CA) is 20. You need to use pythagorean formula in getting the length of AB.

YOUR ANSWER IS (22).

What is the value of a?

Luda [366]

Answer:

a = 62

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

a + 47+71 = 180

Combine like terms

a +118 = 180

Subtract 118 from each side

a+118-118=180-118

a =62

I got 47.01816163 metres. When I tried to round it I got it wrong. Can someone please help me?

DerKrebs [107]

Answer:

28 m

Step-by-step explanation:

The top angle in the triangle = 90° - 62° = 28°

Using the cosine ratio in the right triangle

cos28° = $\frac{adjacent}{hypotenuse}$ = $\frac{25}{x}$

cross- multiply

x × cos28° = 25 ( divide both sides by cos28° )

x = $\frac{25}{cos28}$ = 28.31425... ≈ 28 m

Thus the distance from the top to the crocodile is 28 m
