Answer:

The answer for this question will be 324 square roots

Step-by-step explanation:

The length and width of a rectangle are interchangeable, however we usually use the longer side for the length.

If that's the case, then the square is 18 x 18 = 324 square units.

On the other hand, the square could also be 10 x 10 square units. You choose ! In reality, the length and width, like I said, are interchangeable.

if in a triangle, measure of angle A is 71 degrees, measure of angle B is 42 degrees, and BC= 8, find AC to the nearest hundredt

olasank [31]

Length BC is opposite of angle A and AC is opposite of angle B.

Since we know one set of opposite angles and lengths and looking for the length where we know the opposite angle, we can use law of sines: 

a / sin(A) = b / sin(B) 
8 / sin(71) = b / sin(42) 
b sin(71) = 8 sin(42) 
b = 8 sin(42) / sin(71) 
b ≈ 5.66 units (rounded to 2DP)
