Mathematics

Soloha48 [4]3 years ago
5 0

Step-by-step explanation:

Since, Point E is the midpoint of DF

Therefore,

DE = EF

10x = 4x + 12

10x - 4x = 12

6x = 12

x = 12/6

x = 2

EF = 4x + 12 = 4*2+12 = 8 * 12 = 20

EF = 20

AB = BC

6x + 2 = 9x - 10

10 + 2 = 9x - 6x

12 = 3x

12/3 = x

x = 4

BC = 9x - 10 = 9*4 - 10 = 36 - 10 = 26

What is the equation of a circle with center of (4,2) passing through the point (7,2)
attashe74 [19]

Answer:

(x-4)^2 + (y-2)^2 = 3^2

or

(x-4)^2 + (y-2)^2 = 9 (simplified if needed)

Step-by-step explanation:

-Equation of a circle is:

(x-h)^2+(y-k)^2=r^2 where the center is (h, k) and the radius is r^2.

-Place the center and the point onto that equation:

(7-4)^2+(2-2)^2=r^2

-Then, you solve:

(7-4)^2+(2-2)^2=r^2

(3)^2+(0)^2=r^2

9 +0=r^2

9=r^2

\sqrt{9} =\sqrt{r^2}

3=r

-So, the result is:

(x-4)^2+(y-2)^2=3^2

or

(x-4)^2+(y-2)^2=9 (simplified if needed)

Please help!!
disa [49]

Answer:

C. Scalene triangle

Step-by-step explanation:

What I would do is add all of the angles to 180 and then solve for x.

6x + 10 + 7x + 15x + 2 = 180

28x + 12 = 180

28x = 168

x = 6

Then, plug in 6 for each expression to find each angle

6(6) + 10 = 46

7(6) = 42

15(6) + 2 = 92

Since none of the angles are equal and one of the angles is over 90 degrees, triangle GFH is a scalene triangle
