In a right triangle, the leg adjacent to an angle of 23° is 12 cm long. How long is the leg opposite the 23° angle, to the nearest tenth?

Answers

Answer 1

Answer:

tan55 = x/43

x = tan(55) * 43

x = 61.4 cm

Step-by-step explanation:

Answer 2

The length of the leg opposite the 23° angle, to the nearest tenth, will be 5.1 cm.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

In a right triangle, the leg adjacent to an angle of 23° is 12 cm long. The triangle is given below.

Let 'x' be the opposite side of the angle 23°. Then the value of the variable 'x' is given as,

tan 23° = x / 12

Simplify the equation, then we have

tan 23° = x / 12

0.4244 = x / 12

x = 0.4244 · 12

x = 5.1 cm

The length of the leg opposite the 23° angle, to the nearest tenth, will be 5.1 cm.
