$\bold{\huge{\blue{\underline{ Solution}}}}$

$\bold{\underline{ We \: have \:given \: that, }}$

Distance between the house and tower is 35 m
The height of the tower is 60 m
The height of the house is 25 m

$\bold{\underline{ Now}}$

Height of the house is 25m

$\bold{\underline{ So, }}$

$\sf{ CE = 25m }$

Therefore,

$\sf{ AB = AD - CE }$

$\sf{ AB = 60 - 25 }$

$\sf{ AB = 35 m }$

Now, In Right angled ABC

$\bold{tan Φ =}{\bold{\frac{ AB}{BC}}}$

$\bold{tan Φ =}{\bold{\frac{ 35}{35}}}$

$\bold{ tan Φ = 1 }$

$\bold{ tan Φ = 45 °}$

$\sf{\red{Hence, \: The \:angle \:of \:depression\: is \:45°}}$

What means the same as 6 × 5? A.6^5 B.5 + 5 + 5 + 5 + 5 C.6 + 6 + 6 + 6 + 6

skelet666 [1.2K]

Here is your answer:

In order to find your answer we will have to solve each option separately to see which one equals 6 × 5.

$6^5 = 6\times6\times6\times6\times 6$ <---- Not the answer
$5 + 5 + 5 + 5 + 5 = 25$ <----- Not the answer
$6 + 6 + 6 + 6 + 6 = 35$ <---- Your answer

Therefore your answer is option C "6 + 6 + 6 + 6 + 6 ."

Hope this helps!
