Given:

Given that ABC is a right angled triangle.

The length of AB is 29 units.

Length of BC is 9 units.

The measure of ∠A is x.

We need to determine the value of x.

Value of x:

The value of x can be determined by using the trigonometric ratios.

Thus, we have;


sin \ A=(BC)/(AB)

Substituting the values, we get;


sin \ x=(9)/(29)

Simplifying, we get;


sin \ x=0.3103

Taking
sin^(-1) on both sides, we get;


x=sin^(-1)(0.3103)


x=18.08

Thus, the value of x is 18.08

Hence, the measure of ∠A is 18.08°
