Answer:
The correct answer is 24
Step-by-step explanation:
to solve this you will need to use the pathagreom theorum
a^{2}+b^{2}=c^{2}
A= one side lenth
B= the secons side lenth
C= hypotnuse
It is helpfull to draw out the situation
you know that the latter is 25 ft, that is your hypotnuse
you also know that the 7 ft away from the base of the building is one of the side lenths, lets call it side a
so plug the numbers into the equation
7^2 + b^2 = 25 ^2
you leave b^2 alone because that is the side you are trying to find
now square 7 and 25 but leave b^2 alone
49 + b^2 = 625
now subtract 49 from both sides
b^2 = 576
now to get rid of the square of b you have to do the opposite and square root both sides removing the square of the B and giving you the answer of..........
B= 24
Hope this helped!! I tryed to explain it as simpil as possiable
Solve using the Pythagorean theorem.
The hypotenuse is c.
9x–42=5 is x = 11.
<u>Step-by-step explanation:</u>
9x- 42 = 5...
When we put x = 9
then we will get 81 - 42 =39
put x = 10 then
9(10) - 42 = 90 - 42 - 48
put x = 11
then 9(11) - 42 = 99-42 = 57
So x = 11 is the answer.
1) both have positives signs OR
2) both have negatives signs
