Use the diagram to answer the question. What is the measure of ∠A? Enter the correct value. Do not enter the degree symbol.
forsale [732]

Answer:

Measure of ∠A = 60.07°

Step-by-step explanation:

From the figure attached,

ΔABC is a right triangle,

Measure of side AC = 15 units

and measure of side BC = 13 units

By applying Sine rule in this triangle,

SinA = \frac{\text{Opposite side}}{\text{Hypotenuse}}

Opposite side of angle A = Side AC

and hypotenuse of the triangle = Side BC

SinA = \frac{13}{15}

    A = \text{Sin}^{-1}(\frac{13}{15})

    A = 60.07°

Therefore, measure of angle A is 60.07°.
