Answer:
D
Step-by-step explanation:
use you law of sine
missing angle A = 41
21/sin41=x/sin24 = 13
21/sin41=x/sin115 = 29
The measure of angle A is 41 degrees, the side lengths are 13, and the 29 units option (D) is correct.
In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture
The measure of the angle A = 180 - (115+24)
Angle A = 41 degrees
Using sin law:
21/sin41 = AC/sin24
b = AC = 13 units
21/sin41 = AB/sin115
c = AB = 29
Thus, the measure of angle A is 41 degrees, the side lengths are 13, and the 29 units option (D) is correct.
