Answer:

5

Step-by-step explanation:

The complex number 4 + 2i on the complex plane has coordinates (4,2) and the complex number 7 - 2i has coordinates (7,-2). Thus, the length of a segment in the complex plane with endpoints at 4 + 2i and 7 – 2i is

\sqrt{(4-7)^2+(2-(-2))^2}=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5.

Answer:

5

Step-by-step explanation:

From question statement , we observe that

Two end points of a line segment are given we have to calculate the length of the line segment.

On complex plane,we represent 4+2i as coordinate (4,2) and 7-2i as coordinate (7,-2).

We use distance formula to calculate the length of a line segment.

length = √(x₂-x₁)²+(y₂-y₁)²

Putting given values in above formula , we get

length = √(7-4)²+(-2-2)² = √(3)²+(-4)²

length = √9+16 = √25 = 5

Hence, the length of a segment with end points at 4+2i and 7-2i is 5.

Answer:

a) Yes, HL

Step-by-step explanation:

We\ know\ that:\\Both\ triangles\ are\ right\ triangles. (90\ degree)\\They\ share\ a\ common\ side.\\They\ have\ their\ hypotenuses\ corresponding.\\Hence,\\Through\ HL(If\ the\ hypotenuse\ and\ any\ leg\ of\ the\ triangles\ are\ corresponding,then,\ the\ two\ triangles\ are\ congruent.)

We\ can\ hence,\ conclude\ that\ the\ given\ triangles\ are\ congruent.

I just need to know how to solve this question.
Zarrin [17]

Answer:

x = 62

Step-by-step explanation:

x and 118 form a linear pair (added up, they both equal 180 degrees)

So, 180-118 = 62 which is the measurement of x

Which of these people had balanced their checkbook correctly. Gary: the balance in his check register is $500 and the balance in
otez555 [7]

Gary should be the correct choice because when you balance their checkbook correctly you should have a balanced or equal amount in both your check register and your bank statement.

Good luck! Please let me know if I have chosen the wrong answer. All though I am very confident in my answer.

Answer:

m∠8=120°

Step-by-step explanation:

Given that lines L and M are parallel to each other, keep in mind that ∠1 and ∠8 are opposite exterior angles, so they will be congruent to each other. Therefore, m∠8=120°.
