The measure of an inscribed circle of an angle is the measure of the intercepted arc

Andre45 [30]

Answer:

(the statement does not appear to be true)

Step-by-step explanation:

I don't think the statement is true, but you CAN compute the intercepted arc from the angle.

Note that BFDG is a convex quadrilateral, so its angles sum to 360. Since we know the inscribed circle touches the angle tangentially, angles BFD and BGD are both right angles, with a measure of 90 degrees.

Therefore, adding the angles together, we have:

alpha + 90 + 90 + <FDG = 360

Therefore, <FDG, the inscribed angle, is 180-alpha (ie, supplementary to alpha)

The length of each side of a square is 3 in. more than the length of each side of a smaller square. The sum of the areas of the

dolphi86 [110]

Answer:

Step-by-step explanation:

let the smaller square be A, and the side is a

larger square is B, the side is a+3

Area(A)=a^2

Area(B)=(a+3)^2

a^2+(a+3)^2=425 in^2

a^2+a^2+6a+9=425

2a^2+6a=425-9

2(a^2+3a)=416 we divide by 2

a^2+3a=208

we solve the quadratic function

we will get two roots, a(1)=13, and the negative answer we will ignore

a=13 and the side of the larger square is 13+3=16

The equation s = 20h + 10 predicts Mary's score, s, on her next math test based on the number of hours, h, Mary studies. If the

Flura [38]

Answer:

s= 65

Step-by-step explanation:

The given quation s = 20h + 10

h= number of hours

Where h= 2.75 hours

If we substitute h into given model equation, we have

s = 20(2.75)+ 10

s=55 +10

s= 65

Hence, her score is 65

The following two vectors satisfy the same system of linear equations. u=⎡⎣⎢⎢6−5−5⎤⎦⎥⎥, v=⎡⎣⎢⎢746⎤⎦⎥⎥ Find x and y that make the

kondaur [170]

Answer:

x=-30/71, y=0

Step-by-step explanation:

if a vector satisfies an equation of the form ax+by+cz=0 then the vector is

parallel to the plane ax+by+cz=0, and, the cross product of two vectors results in an orthogonal vector to both.

So, <a,b,c> the normal vector of the plane ax+by+cz=0, can be found as the cross product of the two parallel vetors to the plane:

<a,b,c> = <6,-5,-5>×<7,4,6>= <-10,-71,59>

so, the homogeneous system is:

-10x-71y+59z=0

by replacing the vector <3,x,y> in the system

-30-71x+59y=0

So, there are 2 unknown variables and 1 equation, it means that 1 variable is free

so, y=0 is a random defition and x can be obtain with the equation

-30-71x=0 -> x=-30/71
