Answer: $x=18$ ; $y=6\sqrt{3}$

Step-by-step explanation:

You can write two expressions that are in terms of 'x' and 'y'. This is a right triangle, so Pythagorean's theorem can be used. We can also use the angle to find the sine of 30 degrees.

<u>Pythagorean's Theorem:</u>

The values 'a' and 'b' are the two shorter sides of the triangle, while the value 'c' is the longest side of the triangle; the hypotenuse.

$a^2+b^2=c^2$

$x^2+y^2=(12\sqrt{3} )^2$

$x^2+y^2=12^2*\sqrt{3} ^2=432$

<u>Sine of the Angle:</u>

Sine is defined to be the opposite side divided by the hypotenuse. Let's take the sine of 30 degrees:

$sin(\alpha )=opposite/hypotenuse$

$sin(30)=y/12\sqrt{3}$

$\frac{1}{2} =y/12\sqrt{3}$

$y=6\sqrt{3}$

Plug this value of 'y' into the first expression derived from Pythagorean's theorem:

$x^2+y^2=432$

$x^2+(6\sqrt{3} )^2=432$

$x^2+108=432$

$x^2=432-108=324$

$x=\sqrt{324}$

$x=18$

Use this value of 'x' to solve for 'y' in the expression from Pythagorean's theorem:

$(\sqrt{324})^2+y^2=432$

$324+y^2=432$

$y^2=432-324=108$

$y=\sqrt{108}$

$y=\sqrt{36*3}$

$y=6\sqrt{3}$

Corresponding parts find m

balu736 [363]

Answer:

Angle D is equal to 80.

Step-by-step explanation:

We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.

Triangles' angles always add up to 180.

180 - 70 - 30 = 80

angle D is equal to 80.

Delia is bagging 24 onion bagels and 16 plain bagels for her bakery customers. Each bag will hold only 1 type of bagel. Each bag

Mnenie [13.5K]

<h2>Answer:</h2><h2>8 bagels in each bag, 3 bags of onion, 2 bags of plain</h2>

24 onion bagel

16 normal bagel

We need the GCF (Greatest Common Factor) of 16 and 24 to find the answer.

Factors of 16 = 1, 2, 4, 8, 16

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

What is the GCF? It is 8.

Hence, 8 bagels in each bag.

24/8 = 3 bags of onion bagels

and

16/8 = 2 bags of plain bagels
