Answer: k=-98
Step-by-step explanation: 11-k/2 = 60 11+

This is a vector problem. The distance of drift is in x (horizontal axis).
remember that Sin Ф=opposite/hypotenuse. x represents the opposite side form the angle, and 18 is the hypotenuse.
Sin 2.2°=x/18
18 sin 2.2°=x
.691 ≈x
The ship drifts off course .691 miles every hour. .691 x 5 = 5.69 miles after 5 hours.
Use photomath... but i already did 11 and its -52
Answer:
= 115°
Step-by-step explanation:
Intersecting chord theorem,
"When two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle."
By this theorem.
=
---------(1)
= 40°

= 100° + 60° + 30°
= 190°
By substituting these values in the expression (1)
= ![\frac{1}{2}[40+190]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B40%2B190%5D)
= 115°
Therefore,
= 115°
Answer: 400 units
