Answer:
see explanation
Step-by-step explanation:
using the sine ratio in the right triangle.
sin23° = = ( multiply both sides by 7 )
7 × sin23° = x , then
x ≈ 2.7 ( to the nearest tenth )
----------------------------------------------------
using the tangent ratio in the right triangle
tan x = = , then
x = ( ) ≈ 57.8° ( to the nearest tenth )
Selection D is appropriate.
_____
I would write it differently.
.. 180 -x = "supplement of an angle"
.. 2x +20 = "20 more than twice the measure"
These are said to be equal, so I would write it as
.. 180 -x = 2x +20
Of course, adding x to both sides of this equation makes it
.. (2x +20) +x = 180 . . . . . . matches selection D
