Answer:

15 degreese

Step-by-step explanation:

Given AOB 30 - has to make angle DOB 150 cause that be 180 since DA is the diameter

Also they say DE is the same as EK - 30

now EKA is 180 but you got to subtract that EK 30 = 150

to find C you do 1/2 ( ABD - KA )

1/2 (180 - 150)

is 15

Correct answer gets brainliest

Ilia_Sergeevich [38]

Answer:

sides: isosceles
angles: right

Step-by-step explanation:

At first, lets find the distance from one point to the other.

$d(A,B)=\sqrt{(x_{A}-x_{B} )^2 +(y_{A}-y_{B} )^2 } \\d(A,B)=\sqrt{(2-0 )^2 +(-2-4 )^2 } \\d(A,B)=\sqrt{4 +36 } = \sqrt{40 } = \sqrt{4 * 10 } = 2\sqrt{10}$

The same way, you can find that:

$d(A,C)= 2\sqrt{10}\\d(A,B)= 2\sqrt{20}$

Since the triangle has only its two sides equal to each other (AB = AC),

it's an isosceles one.

As long as the angles are concerned, we gotta "cheat". In other words, we see that:

$AB^2 + AC^2 = (\sqrt{40})^2 + (\sqrt{40})^2 = 40 + 40 = 80\\ AB^2 + AC^2 = 80 = (2\sqrt{20})^2 = BC^2\\AB^2 + AC^2 = BC^2$

By the inverse of pythagorean theorem, we know that if the above equation holds, then we have a right-angled triangle. That is to say that,

A = 90

Since its an isosceles triangle, AB = AC,

B = C = (180 - A)/2 = 45 degrees

A farmer ships oranges in wooden crates that each weigh 15 pounds when they are empty. The total weight of the crate when filled

scoundrel [369]

Answer:

Step-by-step explanation:

Let g represent the weight of the g oranges that were put in the crate in pounds.

From the information given,

The weight of the empty crate is 15 pounds. The total weight of the crate when filled with g oranges is 24.5 pounds.

Therefore, the equation that represents the relationship between the weight of the crate and the number of oranges it contains is

g + 15 = 24.5

g = 24.5 - 15

g = 9.5 pounds

The weight of the g oranges is 9.5 pounds
