or x= twelve-fifths
Option A is correct.
Step-by-step explanation:
We need to find the solution of:

Solving:
Taking square on both sides:

Verifying the solution by putting x = 12/5 in the given equation, we get true result.
So,
or x= twelve-fifths
Option A is correct.

Answer:
12 ft
Step-by-step explanation:
Note that you have a right triangle here, with hypotenuse 13 ft, and base 5 ft. Using the Pythagorean Theorem, we find the height of the upper tip of the ladder as follows:
(13 ft)^2 = y^2 + (5 ft)^2. Then y^2 = 144 ft^2, and y =height= 12 ft

Answer:
1. x= 122(answer on pdf=n)
2. x=38(answer on pdf=s)
7. x=26(answer on pdf=l)
8. x=14(answer on pdf=p)
13. x=22(answer on pdf=b)
14. x=12(answer on pdf=k)
Step-by-step explanation:
Supplementary angle for number 1 so 58+x=180
180-58=x=122
Number 2 is a complimentary angle so 52+x=90
90-52=x=38
Number 7 is a complimentary angle so 64+x=90
90-64=x=26
Number 8 it states that the angles are equal so 4x=56
56/4=x=14
Number 13 is a supplementary angle so (6x-2)+50=180
(180-50+2)/6=x=22
132/6=x=22
Number 14 is complimentary so 8x-6=90
96/8=x=12
