<h3>Yes the triangles are congruent by ASA axiom or congruency .</h3>
Because one side of triangle is equal and two angles are equal . So option 1 is your answer .
The answer to c. Is 8t+12g
Answer:
0
Step-by-step explanation:
On a graph, any line that is horizontal has a slope of zero. Try any points and and plug them into the slope formula equation
(Y2-Y1/X2-X1).
The answer will always be zero.
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
