this is an isoscele triangle, AB = BC, and the angle A is equal angle C.

8y - 7 = 73

8y = 73 + 7

8y = 80

y = 80 : 8

y = 10

------------------------

the sum of the interior angles is 180°

180 - 73 - 73 = 34° (angle B)

6x + 4 = 34

6x = 30

x = 30 : 6 =

x = 5

since this is an isosceles triangle, angle a =angle c

73 = 8y-7

add 7 to each side

80 = 8y

divide by 8

y =10

the sum of all three angles =180

<a +<b+<c = 180

73+6x+4 +73 = 180

add like terms

150 +6x = 180

subtract 150 from each side

6x = 30

divide by 6

x=5

Convert the polar equation r=4sinθ to a Cartesian equation. Answer choices: x^2 + y^2 = 4y x^2 + y^2 = 4x

natali 33 [55]

Start by multiplying both sides by r:

$r = 4 \sin \theta$
$r^2 = 4r \sin \theta$

Since $r^2 = x^2 + y^2$ and $y = r \sin \theta$ , we have that

$\bf x^2 + y^2 = 4y$

In right triangle ABC, B is the right triangle and m C = 30. If AC = 10 what is AB?

nekit [7.7K]

Using the law of sins:

Sin(angle) = Opposite Leg / Hypotenuse

Sin(30) = AB /10

Solve for AB:

AB = 10 * sin(30)

AB = 10 * 1/2

AB = 5

The answer is A.

Erika is painting a rectangular painting. The painting has a length of 12 and a width of 10 inches. Use the Distributive Propert

antiseptic1488 [7]

Given:

Length of the painting = 12 inches

Width of the painting = 10 inches

To find:

The area of the rectangular painting by using Distributive Property to decompose the factor 12.

Solution:

The area of a rectangle is

$A=length\times width$

So, the area of the rectangular paining is

$A=12\times 10$

Using Distributive Property to decompose the factor 12, we get

$A=(10+2)\times 10$

$A=(10\times 10)+(2\times 10)$

$A=100+20$

$A=120$

Therefore, the area of the rectangular painting is 120 square inches.
