Find the lengths of the missing side . Simplify all radicals !!!<br> help mee!!!!!!
larisa86 [58]

Answer:

e = 13\sqrt{2}

f = 13\sqrt{2}

Step-by-step explanation:

The ∆ given is an isosceles ∆ with a right angle measuring 90°, and two congruent angles measuring 45° each.

Using trigonometric ratio formula, we can find the lengths of the missing side as shown below:

Finding e:

sin(\theta) = \frac{opp}{hyp}

sin(\theta) = sin(45) = \frac{\sqrt{2}}{2}

hyp = 26

opp = e = ?

Plug in the values into the formula

\frac{\sqrt{2}}{2} = \frac{e}{26}

Multiply both sides by 26

\frac{\sqrt{2}}{2}*26 = \frac{e}{26}*26

\frac{\sqrt{2}}{2}*26 = e

\frac{\sqrt{2}}{1}*13 = e

13\sqrt{2} = e

e = 13\sqrt{2}

Since side e is of the same length with side f, therefore, the length of side f = 13\sqrt{2}

Answer:

<em>Daniel does have enough money to make this car payment</em>

Step-by-step explanation:

<u>Addition and Subtraction</u>

Daniel has an initial balance of $460.63 on this checking account.

He must pay $85.23 for groceries.

The new balance is $460.63 - $85.23 = $375.40

He then pays $81.34 for his cell phone bill. The balance is now $375.40 - $81.34 = $294.06.

He receives a shopping refund of $52.13 that adds up to this balance that now is: $294.06 + $52.13 = $346.19.

Daniel has to make his $264 car payment. The balance is $346.19, thus:

Daniel does have enough money to make this car payment
