That is a isosceles triangle, therefore x and the top angle are the same.
There’s 180 degrees in a triangle.
Therefore:
(180 - 38)/2 = x
142/2 = x
71 = x
I think that a linear equation can have no solution, one solution, or infinitely solutions. It just depends on what is the equation. That's what I think
Answer:
-10x5 + 8x4 - 7x3 - 20x2 - x + 18
Step-by-step explanation:
Answer:
-9
Step-by-step explanation:
