If l is parallel to m, what is the relationship between 3 and 7?

a.
they are congruent because they are alternate external angles.
b.
they are congruent because they are corresponding angles.
c.
they are supplementary because they are corresponding angles.
d.
they are supplementary because they are alternate internal angles.

B.

Step-by-step explanation:

they are correseponding angles so that means that they aer congruent because the lines are parallel

step-by-step explanation: 4 cause 2+2=4

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
