20 + 2x + 12 + 2x + 8
40 + 4x
Answer:
C
Step-by-step explanation:
Let say for example, the triangle is named ∆ABC, and the two angles given are <A and <B with a given side, c, opposite to the third angle (<C).
Since sum of triangle = 180°, we can find the third angle by saying:
m<C = 180 - (m<A + m<B).
Having found the third angle measure, <C, we can mow apply the Law of Sines to find the length of the other two sides (a and b) that are opposite to <A and <B respectively.
Answer:
E
Step-by-step explanation:

Put the the E coordinates.
