The answer to ur question is 20 degree angles cause each dot is 5 degrees so that would equal 20 after you split them up
Answer:
120
Step-by-step explanation:
The sum of the angles is 180 since it forms a straight line
2x+ x+90 = 180
Combine like terms
3x +90=180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide each side by 3
3x/3 = 90/3
x = 30
We want angle DBC = x+90
= 30+90
=120
So hmm check the picture below
both ships leave at the same time, one is going 16mph, the other 20mph, 2hrs later on the road
at 16mph well, 2hrs is just 16+16, or 32 miles away
20mph for 2hrs, is 20+20, or 40 miles away
using the law of cosines

again, recall, the angle is in degrees, so, when taking the cosine, make sure your calculator is in Degree mode
