The angle of elevation of a ladder leaning against a wall is 60⺠and the foot of the ladder is 4.6 m away from the wall. the length of the ladder is: . 2.3 mb. 4.6 mc. 7.8 md. 9.2 m

9.2m

Explanation: According to SOH CAH TOA

Cos 60° = Adjacent/Hypotenuse (CAH)

Given theta = 60° which is the elevation angle

Adjacent side which is the base of the set up (distance from the ladder to the wall) is 4.6m

Cos60° = Adjacent/Hypotenuse

Cos 60° = 4.6/Hypotenuse

Hypotenuse = 4.6/cos60°

Hypotenuse = 9.2m

The hypotenuse always the slanting and longest side of the set up which is the ladder according to the question.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
