Answer:

Y = 12 x = 13

Step-by-step explanation:

Triangular Sum says that the three angles in a triangle is 180˙.

So, <DAC + <ACD + <CDA = 180.

1. Substitute the angle measures into the equation above.

<DAC + <ACD + <CDA = 180

(3y + 2) + 52 + 90 = 180

3y + 144 = 180

- 144 -144

3y = 36

3 3

y = 12

m<DAC & m<CAB add up tp 90.

2. <DAC + <CAB = 90

38 + 4x = 90

- 38 . - 38

4x = 52

x = 13

Triangle DNO has vertices at D(5, 8), N(– 3, 10), and O(– 3, 6). If vertex D is translated 4 units to the right, the best name f

prisoha [69]

Using distance between two points to find the lengths of the edges of the triangle, the correct option is:

b. Isosceles

The distance between two points, $(x_1,y_1)$ and $(x_2,y_2)$ , is given by:

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Vertex D is translated 4 units to the right is (9,8).

The lengths of the edges are:

$DN = \sqrt{(9 - (-3))^2 + (8 - 10)^2} = \sqrt{12^2 + 2^2} = \sqrt{148}$

$DO = \sqrt{(9 - (-3))^2 + (8 - 6)^2} = \sqrt{12^2 + 2^2} = \sqrt{148}$

$NO = \sqrt{(-3 - (-3))^2 + (10 - 6)^2} = \sqrt{0^2 + 4^2} = 4$

Two edges of the same length, hence, it is an isosceles triangle, given by option b.

What is the zero for 2x2-7=4

rosijanka [135]

2x^2-7=4
subtract 4 from both sdies
2x^2-11=0
therefor
2x^2=11
divide by 2
x^2=5.5
square root both sdies
x=-2.345 or 2.345

Anastasy [175]

Answer:

$286.80

Step-by-step explanation:

First, find the price after the 150% markup:

478(1.5)

= 717

Now, calculate the price with the 60% discount:

717(0.4)

= 286.8

= $286.80
