Step-by-step explanation:
Irrational number has unsolvable root overs.
Last two are now our options

Hence its not irrotational.
Hence
Option C is irrational.
Answer:
256−1
Step-by-step explanation:
Y=-4x+3 is already in slope intercept form. Graphed it looks like this
From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:
Now, since interior angles of any triangle add up to 180 degrees, we have

By combining similar terms, we get

Then, x is given as

Therefore, the answer is x=90 degrees
