Step-by-step explanation:
Using the cosine and tangent ratios in the right triangle
cos41° = =
=
Multiply both sides by VX
VX × cos41° = 7 ( divide both sides by cos41° )
VX = ≈ 9.3
-----------------------------------------------------------------------
tan41° = =
=
Multiply both sides by 7
7 × tan41° = WX, thus
WX ≈ 6.1
-------------------------------------------------------------------------
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180° for ∠ X
∠ X = 180° - (90 + 41)° = 180° - 131° = 49°
