Two lines intersect to form an X. The measure of one angle is 58∘. Question 1
Part A

What is the measure of one of the angles sharing a side with the 58∘ angle?

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
