Answer:
59 degrees
Step-by-step explanation:
law of cosines states that
for sides A B C and angle c opposite to side C,
cos(b) =
cos-1(23/45) = b
b = 59
Answer:59
C2=a2+b2-2ab cosC
13x13=15x15+6x6-2(15)(6)cosC
169=225+36-180cosC
169=261-180cosC
-92=180cosC
-92/-180=cosC
C=arccos92/180. On your calculator it will say cos-1
C=59.23 or m<B = 59. Rounded to the nearest degree.
I believe the answer is 145
725÷5= 145
Hi!
I can help you with joy!
The answer is 2x= 6x.
This is an example of direct variation!
