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

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 =

Opposite side of angle A = Side AC

and hypotenuse of the triangle = Side BC

SinA =

    A =

    A = 60.07°

Therefore, measure of angle A is 60.07°.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

table 3 represents a direct variation function. : )
