Right triangle ABC is shown. Which of these is equal to cos(A)?A) cos(B)
B) cos(C)
C) sin(B)
D) sin(C)

Answers

Answer: C

cosA=AC/AB

sinB=AC/AB

hence cosA=sinB

Answer:

C).

Step-by-step explanation:

Since angles A and B are complementary, their cofunctions are equal. So, cos(A) = sin(B).

PLEASE HELP!Which is the correct classification of square root of 18?

A. irrational number, non-repeating decimal
B. irrational number, terminating decimal
C. rational number, terminating decimal
D .rational number, non-repeating decimal

Answers

The correct classification of the square root of 18 is: A. irrational number, non-repeating decimal.

To determine the classification of the square root of 18, let's break down the steps:

1. Calculate the square root of 18:

$√(18) \approx 4.24264068712$

2. Rational or Irrational?

The square root of 18 is an irrational number because it cannot be expressed as a fraction of two integers, and it is non-terminating, non-repeating decimal.

Rational numbers can be expressed as fractions, and their decimal representation either terminates (e.g., 1/4 = 0.25) or repeats in a pattern (e.g., 1/3 = 0.333...).

Since $√(18)$ cannot be expressed as a simple fraction, and its decimal representation continues infinitely without repeating, it is classified as an irrational number, non-repeating decimal.
