➷ It would help if you drew it out as a triangle
You will notice that you need to use tan
tan70 = 39/x
x = 39/tan70
x = 14.194
The correct option would be 14.2 ft
You will need to use tan
tan51 = 6/x
x = 6/tan51
x = 4.8587
The correct option would be 4.9m

Answer:
x = 30
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
x + 4x + 30 = 180
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
