<h2>Answer:</h2>

<u>Yes he is correct</u>

<h2>Step-by-step explanation:</h2>

Given a triangle ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side. In the words of Euclid: In any triangle two sides taken together in any manner are greater than the remaining one.

If we add the two sides 12 and 18 we get 30 so the third side must be greater than 30. He said greater than 6 so he is right too

An Individual Retirement Account (IRA) has $17 comma 000in it, and the owner decides not to add any more money to the account

Umnica [9.8K]

Answer: The owner reaches at Rs. 56438.28 after 30 years.

Step-by-step explanation:

Since we have given that

Sum = Rs. 17000

Rate of compounded daily = 4%

Number of years = 30 years

So, Using "compound interest formula" we get that :

$A=P(1+\dfrac{r}{n})^{nt}\\\\A=17000(1+\dfrac{0.04}{365})^{365\times 30}\\\\A=17000(1.000109589)^{10950}\\\\A=56438.28$

Hence, The owner reaches at Rs. 56438.28 after 30 years.

90 + 40 + 5z + 10 = 180

5z + 140 = 180

5z = 40

z = 8
