Answer 1

x = 13.7

Explanation:

The angle at the top of the triangle = 90° - 17° = 73°

The left side of the triangle is x ( opposite sides of a rectangle )

Using the cosine ratio in the right triangle

cos73° =
`(adjacent)/(hypotenuse)` =
`(x)/(47)`

Multiply both sides by 47

47 × cos73° = x, hence

x ≈ 13.7

Answer 2

13.74

Explanation:

the top right angle is 90 (opposite angles in a quadrilateral add up to 180). use the sine rule. x = 47/sin 90 × sin 17

= 13.74
