Ответ:
Option A is correct.
Step-by-step explanation:
Given:
Angles of the right angled triangle : 60° , 30° and 90°
Measurement of the side opposite to angle 60°, b is 9√3 yd
To find: Missing measures of the sides.
Vertex are marked and pic is attached.
We use Law of sines to find missing values.
Now, Consider
a = 9 yd and c = 18 yd
Therefore, Option A is correct.
