Find the missing side in each triangle using any method.

Answers

I used the Pythagorean theorem for both triangles.Small Triangle) The missing side is equal to 13We have to solve the hypotenuse here:5² + 12² = ?(5 x 5) + (12 x 12) = 169The square root of 169 is 13Big Triangle) The missing side is equal to 24We have to solve for a leg here:26² - 10² = ?(26 x 26) - (10 x 10) = 576The square root of 576 is 24Please let me know if I am wrong.

The missing side lengths of the right triangles are AC = 13 and DE = 24.

What is the Pythagorean theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given the two right triangles.

The hypotenuse of the first right triangle is given by:
AC² = 5² + 12²

AC² = 25 + 144

AC² = 169

AC = 13

The length of the leg in the second triangle is given by:

DE² = 26² - 10²

DE² = 676 - 100

DE² = 576

DE = 24

Hence, the missing side lengths of the right triangles are AC = 13 and

DE = 24.

The student council is organizing a school fair. Council members are making signs to show the prices for admission and for each game a person can play. If the school admission is $2 and the price per game is 25 cents, Let x represent the number of games. Which expression can you use to determine the total amount (in dollars) a person pays for admission and playing x games?

Answers

Answer:

$2 + 0.25x

Step-by-step explanation:

The expression would be

Let us assume the x be the number of games

And the school admission is $2 plus the price of game is 25 cents

So, based on the above information

The expression to determine the total amount is

= $2 + 0.25x

Answer:

x = 12°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

So,

39° + 53° + 4° + 7x = 180°

Add all the numbers on the left up.

96° + 7x = 180°

Subtract 96 from both sides.

7x = 84°

x = 12°

Hope this helps!

Answer: x= 12

Step-by-step explanation:

Triangle angle sum theorem says that the interior angles of a triangle sum to 180 degrees. Set the sum of all of these angles equal to 180 to solve. 39+53+ (4+7x) = 180. Combine like terms. 96 +7x = 180. Subtract 96 from both sides. 7x = 84. Divide both sides by 7. X = 12

PLEASE HELP QUICKLY!!

Answers

Answer:

79

Step-by-step explanation:

Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.

m4 = 79 because 180 - 101 = 79
