Answer:
135°
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 720
Two of the angles are right (has 90°)
so 4x + 180 = 720 subtract 180 from both sides
4x = 540 divide both sides by 4
x = 135°
Put p(x)=0.
2x-1=0 will give x=1/2. This means, If x=1/2 is given to the polynomial p(x), it will give a zero. P(1/2)=0.
