Answer:
65 degrees
Step-by-step explanation:
85 + 30 = 115
180 - 115 = 65
Verify:
a + b + c = 180
85 + 30 + 65 = 180
180 = 180
Answer:
28.9
Step-by-step explanation:
Using cosine, we get the equation cos(21)=x/31. Solving cos(21), we get about 0.933. Then we multiply by 31 to get about 28.9.
Answer:
There is not enough information to prove the congruence
Step-by-step explanation:
There is not enough information to prove the congruence because we would need to be given at least 3 equal elements (angles and sides) between the triangles. But in this problem we are only given the fact that 2 sides are equal in both triangles, which as I mentioned earlier is not enough.
