A tangent is always perpendicular to the radius at the point of tangency.
A right angle.
Answer:
B.) √3/2
Step-by-step explanation:
By definition of supplementary angles,
∠ABD + ∠BDE = 180
5x + 17x - 18 = 180
22x = 198
x = 9
∠ABD = 5(9) = 45°
∠BDE = 180 - 45 = 135°
Answer:
x > -1
Step-by-step explanation:
Divide each term by 17 and simplify.
