Answer:

Y=59 Z=93

Explanation:

To find Z, you have to know the line is equal to 180 degrees. You then subtract 180-87=93 that’s how you get Z. Then with that you know that 34+Y is going to equal 93 because they are across from each other. I forgot what that property is called, but yeah. Then you subtract 93-34=59 there you go hope that helps :)

Leto [7]

Answer:

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.

Step-by-step explanation:

Future value with annuity:

The future value formula, for an annuity, is:

FV = \frac{P((1+r)^{n} - 1)}{r}

An annuity means that a number of payments happen during the period(an year, for example.

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

1000 € each year, so P = 1000

Interest rate of 6%, so r = 0.06

One application per year for 8 years, so n = 8

Total amount:

FV = \frac{1000((1+0.06)^{8} - 1)}{0.06} = 9897.47

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.
