Solve a triangle with a=25, b=30, and c= 160°
(picture provided)

Option d.

Step-by-step explanation:

For this problem we have 2 sides of a triangle (a and b) and the angle between them C = 160 °.

We have a triangle of type SAS.

We have:

a=25

b=30

C= 160°

Then we use the law of cosine.

Now we substitute the values in the formula to find c

Now we use the cosine theorem to find B. (You can also use the sine)

Finally:

its c or d   take a lucky guess my dude
