Step-by-step explanation:
Solve 2x+7=-1
2x. =-8
x. =-4
Answer:
<h2> 39°</h2>
Step-by-step explanation:
A radius to the tangent point always forms a right angle with the tangent:
m∠XWY = 90°
So:
90° + 58° + x - 7° = 180°
141° + x = 180°
x = 39°
You can use the trigonometric identity

.

The requirement that

eliminates -1/6 from being another solution.
