Answer:
5
Step-by-step explanation:
Rip
Angle x = 30 degrees
Angle y= 100 degrees
Angle z = 50 degrees
Sum of the angles = 180 degrees
19, cuz 4x19 is 76 and 72<76
Answer:
11196.15 km
Step-by-step explanation:
Consider the attached diagram
If the Airplane is at point A and the floating debris at point C, we want to determine the horizontal distance |AB| before they fly over it.
Using trigonometry

Cross multiply
|AB|X Tan 15 =3000
|AB| =
=11196.15 km
Therefore, the horizontal distance |AB| before they fly over it is 11196.15 km
The measure of ∠C is 54°.
<h3>To solve the problem :</h3>
let us assume that line n is a mirror.
∴ ∠A = ∠A' = 59°
∠B = ∠B' = 67°
∠C = ∠C'
According to property of triangles :
Sum of all angles of a triangle is 180°.
∴ A + B + C = 180°
59 + 67 + C = 180
C = 
C = 54°
<h3>∴ The measure of ∠C is 54°.</h3>
