Find the height a 17-foot ladder can reach on the side of a building when it hits the ground at a 65° angle.
A. 7.2 ft
B. 15.4 ft
C. 36.5 ft
D. 48 ft
E 224 ft

SHOW EXPLANATION

B. 15.4 ft

Step-by-step explanation:

this answer, without any formulas used, can be answered correctly and logically.

answer c, d and e are eliminated as the opposite side cant be greater than the hypotenuse.

now we have to find which is correct between a and b

the answer will be 'B' as the value of sine of an angle keeps increasing as the angle itself increases. thus, giving a bigger value of the opposite side (required height). as 15.4 ft.

mathematically,

sin65° = x/17

17 × sin65° = x

where x is height of the side of the building.

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text =

Remaining part =

Remaining part =

Therefore, a newspaper;s cover page fill with  Photograph =

If the article about endangered species= of text

Therefore, the article about endangered species=

Hence,  the article about endangered species is of the cover page.
