If the hypotenuse of a right triangle is 20 cm and one of the legs is 16 cm, how long is the other leg? 2.8
12
24
144

Answers

Answer 1

Answer: Because this is a triangle and we know that we can use the Pythagorean Theorem to find the hypotenuse we just plug in the numbers. But because you have the hypotenuse already you will subtract the leg from the hypotenuse.

A^2+B^2=C^
16^2+B^2=20^2
256+B^2=400 subtract 256 from both sides
B^2=144 now take the square root of both sides
B=12

The second leg is 12 cm long. Your answer is B, the second answer.

|2x + 4| > 14
2x+ 4 = 14 2x + 4 = -14
x = 5 or x = - 9
2*5 = 10 +4 = 14 Yes
2*-9 = -18 + 4 = - 14 Yes
2x > 10 2x < - 18

Select the correct answer from the choices given(13 + 4i) + n = 0
What is n?

a. 0

b. 1

c. –13 + 4i

d. –13 - 4i

Answers

In equating a complex number to 0, we must add an opposite form of the equation, where the values of the real and imaginary parts are the same as the original, but have opposing signs. In the case of (13 + 4i), we have to add (-13 - 4i) to equate it to 0. Among the choices, the correct answer is D.

Answer:

d -13-4i
