Hi there! The answer is B. -7 or 7
The angles in a quadrilateral always add up to 360°. Therefore the angle of P is

So the angle of P is 49° and equals x^2. Therefore we get the following equation

Take the square root of both sides

OR

Since the angle must be positive, the value can as well be -7 as 7 (because the square of both of these numbers is 49°). Hence, the answer is B.
Answer:
It is the 5,280 feet / 1 mile.
Because there are 5280 feet in one mile.
And to convert from hours to seconds you should use 60 minutes / 1 hour and 60 seconds / 1 hour
Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
y-y1=m(x-x1)
y-4=0(x-2)
y-4=0
y=0+4
y=4
Answer:
48
Step-by-step explanation:
4/6 = 2/3
2/3 times 72 = 48
Answer:∠1 and ∠5
Step-by-step explanation:
(A) ∠3 and ∠6 forms the interior angles on the same side of the transversal. Thus, this option is incorrect.
(B) ∠1 and ∠4 forms the linear pair on the straight line a, thus this option is incorrect.
(C) ∠1 and ∠5 forms the corresponding angle pair, thus this option is correct.
(D) ∠6 and ∠7 forms the linear pair on the straight line a, thus this option is incorrect.
