Answer:
See explanation
Step-by-step explanation:
Consider triangles ABC and DEC. In these triangles,
- - given
- - given;
- as vertical angles.
So,
by SAS postulate (two sides and angle between these sides of one triangle are congruent to two sides and angle between these sides of another triangle, so triangles are congruent).
Congruent triangles have congruent corresponding parts, hence,

lol hope helps :D
It’s better if you do but now you don’t have to.
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:
2. x= 60° because a triangle is 180°
