Help with special right triangle please
Ahat [919]

Answer:

Step-by-step explanation:

Looking at the right angle triangle that contains x and y, we would apply trigonometric ratio to determine x an y. Taking 60 degrees as the reference angle,

Hypotenuse = y

Adjacent side = x

Opposite side = 36

Therefore,

Sin # = opposite side / hypotenuse

Sin 60 = 36/y

y = 36/Sin60 = 36/0.8660 = 41.57

Cos # = adjacent side/hypotenuse

Cos 60 = x/41.57

x = 41.57Cos 60 = 41.57 × 0.5 = 20.785

Sin45 = z/36

z = 36Sin45 = 36 × 0.7071 = 25.4556

Mike makes 4 dozen cookies. He brings 75% of them for a party at his school. How many did he bring?
baherus [9]

Answer:

He brought 3 dozen cookies

She ate \frac{2}{5} of the bag of Doritos

She read 25 books

Step-by-step explanation:

∵ Mike makes 4 dozen cookies

∵ He brings 75% of them for a party at his school

- Multiply 75% by 4

∵ 75% = \frac{75}{100}=\frac{3}{4}

∴ He brought = \frac{3}{4} × 4

∴ He brought = 3

He brought 3 dozen cookies

∵ Sam bought a bag of Doritos

∵ She ate only 40% of them

∵ 40% = \frac{40}{100}=\frac{2}{5}

∴ She ate = \frac{2}{5} × 1

∴ She ate = \frac{2}{5}

She ate  \frac{2}{5} of the bag of Doritos

∵ Jamie took 50 books from the library

∵ She only read half of her whole stack

- Multiply half by 50

∴ She read = \frac{1}{2} × 50

∴ She read = 25

She read 25 books
