The straight line distance between two cities A and B is 223 km. The straight line distance between cities A and C is 152 km. The straight line distance between cities B and C is 285 km. Find the measure of the angle when standing at city C between the lines of sight to cities A and B.

Angle between the lines of sight to A and B = 50.94°

Step-by-step explanation:

Distance between the cities A and B = 223 km

Distance between the cities  B and C = 285 km

Distance between the cities  A and C = 152 km

By applying cosine rule in triangle ABC,

AB² = AC² + BC² - 2(AC)(BC)CosC

(223)² = (152)² + (285)² - 2(152)(285)CosC

49729 = 23104 + 81225 - (86640)CosC

CosC =

CosC = 0.630194

C =

C = 50.94°

Therefore, angle between the lines of sight to cities A and B is 50.94°

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
