Answer:
x=18
Step-by-step explanation:
A triangle ALWAYS have overall angles of 180 degrees.
When we look at this triangle, it should come to familiarity that this is a 45 45 90 triangle. This is a special type of isosceles right triangle.
But without knowing this, we can still solve this problem.
Since the triangles' overall angle is 180 and we know 45 and 45 of the two other angles, let's subtract that together to find out the overall angle where we are trying to find x.
180-45-45=90
This means that the expression 4x+18 is equal to 90, since that's the leftover angle amount.
Let's solve that equation now.
4x+18=90 Let's get rid of the 18 by subtracting it on both sides.
-18 -18
4x=72 Isolate the x by dividing both by 4.
x=18
In this problem, x is equal to 18.
Since the sides are congruent so are the angles (SSS) so 3x+3x+3x=180 because all the angles in a triangle add up to 180 degrees
9x=180
X=20
So the answer is x =20
