What is the length of the hypotenuse of the triangle?

Answers

Step-by-step explanation:

Hey there!

Here;

ABC is a Right angled triangle.

Taking reference angle as angleA.

Now;

Hypotenuse (h) = AB

Perpendicular (BC)= 24 ft.

Base(AC)= 10 ft.

Now, Using Pythagoras relation;

[tex]h = \sqrt{ {p}^{2} + {b}^{2} } [/tex]

Put all values.

[tex]h = \sqrt{ {24}^{2} + {10}^{2} } [/tex]

Simplify it.

[tex]h = \sqrt{576 + 100} [/tex]

[tex]h = \sqrt{676} [/tex]

Therefore, h= 26ft.

ANS: OPTION A.

Hope it helps....

Michael wants a new iPhone. The total cost of the phone is $1249. He can pay $43 down with so much each month added to his bill for 24 months. How much extra will be added to each bill for the next 2 years?

Answers

Answer:

7.25 dollars

50.25 - 43 = 7.25

$7.25. ($50.25-$43.00=$7.25)

Sammy buys his clothes at SuperDuper Discount Store. On Saturday, he bought shoes regularly priced at $40 for 25% off, and a jacket regularly priced at $100 for 30% off. What is the total amount that he will have to pay? (Omit sales tax.)

Answers

you would have 10% chance

Step-by-step explanation:

I know, that's probably a lot to take in! :D

40 × 25% = 10

40 - 10 = 30

The final price of the shoes is $30.

100 × 30% = 30

100 - 30 = 70

The final price of the jacket is $70.

30 + 70 = 100

A N S W E R:

The total price of the items Sammy bought (no including sales tax) is $100.
