Question

AB = 2, BC = 3, AC = 5. Triangle ABC is a right triangle. Angle A = ?

a) 30 degrees
b) 45 degrees
c) 60 degrees
d) 90 degrees

Answer 1

To find angle A in triangle ABC, we can use the inverse sine function. Using the given information, we can see that AB is the side opposite angle A and AC is the hypotenuse of the right triangle. Therefore, angle A is approximately 23.6 degrees.

Step-by-step explanation:

To find angle A in triangle ABC, we can use the inverse sine function. Using the given information, we can see that AB is the side opposite angle A and AC is the hypotenuse of the right triangle.

Sine(A) = Opposite/Hypotenuse

Sine(A) = AB/AC

Sine(A) = 2/5

Therefore, angle A is approximately 23.6 degrees.
