Question

Solve for side length x. Round to the nearest tenth.

Answer 1

3.1 rounded to the nearest tenth

Explanation:

Using Sine Rule;

Sin A / a = Sin B / b = Sin C / c

Which is also as Sin M / m = Sin N / n = Sin P / p

Working with M and N;

Sin 15 / x = Sin 90 / 12

Sin 15 / x = 1 / 12 (cross multiply)

Making x the subject of the formula

x = 12 * Sin 15 = 3.10 = 3.1 rounded to the nearest tenth
