What is the value of d?<br><br><br>Round your answer to the nearest tenth.

Sergeeva-Olga [200]

Answer:

11.9 mm

Step-by-step explanation:

We can find d by applying the cosine rules.

d² = 21² + 27² - 2(21)(27) cos (25)

d² = 441 + 729 - 1027.75

d² = 142.25

d = √142.25

d = 11.9 mm (nearest tenth)
