Question

Please tell me the answer

Answer 1

Answer:

5 feet   and   18

Step-by-step explanation:

8  : The two ladder will form Right angled triangle.

Length of ladder will be the hypotenuse.

Third side of Right angled triangle having sides 37ft and 35ft

= √37² - 35²= √(37+35)(37-35) = √72*2=√144=12ft

Third side of Right angled triangle having sides 25ft and 24ft

=√25²-24²= √(25+24)(25-24) =√49*1 = √49 = 7ft

Distance between foot of ladder = 12-7 =5ft

9 : (20 + x) ² = 784

Square Root both sides , We get,

=( 20 + x) = √784

=(20 + x) = 28

x = 28 - 20

= x = 18

Answer 2

Answer:

8) 35 feet - 24 feet= 11 feet

9) $(20+x)^{2}$= 784

Lets take out square roots of Both Sides.

=$(20+x)^{2}$=784

=20+x=28

=x=28-20=8

Verification=

$(20+8)^{2}$=784

=$28^{2}$=784
