Answer:
Step-by-step explanation:
Midpoint of line segment is calculated as
-----------(1)
Here
Substituting values in equation (1)
LN is 180 degrees
180 - 41 = x
x = 139 degrees

H = 30.25 hours
c = 15(30.25) = 453.75
c = 453.75 + 245
c = 698.75
Answer:
40 degrees
Step-by-step explanation:
A triangle solver tool can find the angle easily. It is 39.8°, which rounds to 40°. Apps are available on some calculators, on the Internet, and for iOS and Android phones and tablets.
___
You may be expected to solve this using the Law of Cosines. If we name the sides ...
the law of cosines tells us the relationship is ...
c² = a² + b² -2ab·cos(θ)
Then the angle is ...
θ = arccos((a² +b² -c²)/(2ab)) = arccos((3.0625 +9 -4)/(2·1.75·3))
= arccos(8.0625/10.5) ≈ 39.838° ≈ 40°
