A vertical pole of length 3 m casts a shadow of 7 m and a tower casts a shadow of 28 m at a time. Find the height of tower |
|
Answer» ong>Step-by-step explanation: Height of pole=AB=6 m Length of shadow of pole =BC=4 m Length of shadow of tower=EF=28 m In △ABC and △DEF ∠B=∠E=90 ∘ both 90 ∘ as both are vertical to ground ∠C=∠F (same elevation in both the cases as both shadows are CAST at the same time) ∴△ABC∼△DEF by AA SIMILARITY criterion We know that if two triangles are similar, ratio of their sides are in proportion So, DE AB
= EF BC
⇒ DE 6
= 28 4
⇒DE=6×7=42 m Hence the height of the tower is 42 m please add to brainlist and follow me and thanks. I will follow U |

Find the value of ✓2 by using long division method |
|
Answer» By using the LONG division method, it is possible to find the VALUE of square roots of any number. The steps for finding the value of root 2 is given below: Step 1: The number 2 can be written as 2.000000, i.e., 2 = 2.000000 Step 2: Take the perfect square which is below 2. So the perfect square below 2 is 1. Step 3: Write the number 1 in both divisor and quotient place and subtract 1 from 2, you will get the remainder 1. Step 4: Next write down two zeros and write down after 1 and take the decimal point after 1 in the quotient. Step 5: Now add the divisor part with the same number that we have taken already, .i.e. 1, we will get 2 and write down the number in the divisor place opposite to 100. So, after number 2, we have to take the number and the same number has to be taken in the quotient place also. So, when you take the number 4 after 2 and the same number has to be written in the quotient. Because when you multiply 24 with 4, you get 96 which is closer to the number 100. Finally, subtract 96 from 100 and write down the remainder. Step 6: Now again write down two zero’s and repeat step 5. Step 7: Finally, you get the quotient value as 1.41421 which is approximately equal to 1.414. hope hope it's helpful brainliest answer and follow me and give me FIVE stars and just thanks |
