Question

What is the length of side s of the square shown below?

Answer 1

Answer:

this is sine rule in trigonometry therefore:

• sin90 = sin45

8. S

• S sin90 = 8*sin45
• S=8*sin45

sin45

• S=5.656854249

1

• S=5

Step-by-step explanation:

therefore S is 5

Answer 2

Answer: S = 5.6569

Step-by-step explanation:

Given; let A=45° a = s B=90 ° b=8

using the sine rule;

sinA / a = sin B / b

sin45° / s = sin90° / 8

cross multiply

s × sin 90° = 8 × sin 45°

s × sin 90° = 8 × 0. 7071

s × 1 = 5. 6569

s = 5. 6569

Therefore; the length of the square is 5. 6569
