Answer:
Angle A is 59°
Explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
A = ?
o: opposite = 6
h: hypotenuse = 7
sin A = o/h
cos A= a/h
tan A = o/a
we see that it has (angle, hypotenuse, opposite)
we look at which meets those data between the sine, cosine and tangent
is the sine
sin A = o/ah
Now we replace the values and solve
sin A = 6 / 7
A = sin^-1 (6 / 7)
A = 58.997
round to the nearest hundredth
58.997 = 59°
Angle A is 59°
