3449995000 is what I got, I did 3.45x10^9 and then used that number and subtracted the answer from 0.5x10^4 to get the final answer, if that makes any sense.
Answer: Vertical angles are congruent.
Step-by-step explanation:
In the given picture, NS and RT are intersecting line segments, intersects at point Q.
We know that when two lines intersect to make an cross, angles on opposite sides of the cross are called vertical angles. These angles are equal by the theorem that says Vertical angles are congruent.
⇒∠NQT ≅ ∠SQR
Therefore, the reason that justifies the step 2 :- ∠NQT ≅ ∠SQR is "Vertical angles are congruent" in the proof.
The side length of the square is also 1.
Answer:
A
Step-by-step explanation:
The horizontal side is 8 units long. By Pythagorean, the equal side lengths are 5, so 5 + 5 + 8 = 18.
