AlekseyPX3 years ago
3 0

Answer:

a = 4\sqrt{5}

Step-by-step explanation:

pythagorean theorem:

a² + 8² = 12²

a² + 64 = 144

a² = 80

a = \sqrt{80}

a = \sqrt{4}·\sqrt{4}·\sqrt{5} which simplifies to be 4\sqrt{5}

Find the measure of DB (a curvy line is on top of DB btw)
klasskru [66]

Answer:

Arc DB = 146

x = 5

Step-by-step explanation:

Remark

The relationship between the large arc, the small arc and the intersecting angle is

1/2 (large arc - small arc) = intersecting angle.

Givens

Large arc = 25x + 21

Small arc = 96

5x

Solution

1/2*(25x + 21 - 96) = 5x*2            Multiply both sides by 2

25x + 21 - 96 = 10 x                     Combine      

25x - 75 = 10x                             Subtract 25x from both sides

-75 = 10x - 25x

-15x = -75

x = 5

DB = 25x + 21

DB = 25*5 + 21

DB = 125 + 21

DB = 146

Tell me if this is not in the choices.

The system of equations x + 2y = 6 and x – 4y = 0 is graphed below. What is the solution to the system of equations?
blagie [28]

Step-by-step explanation:

x + 2y = 6....(1) \\  \\  x - 4y = 0\\ \implies \: x = 4y....(2)\\  \\ from \: equations \: (1) \: and \: (2) \\ 4y + 2y = 6 \\   \therefore \: 6y = 6 \\  \\ \therefore \: y =  \frac{6}{6}  \\  \\  \huge \red{ \boxed{ \therefore \: y =  1}} \\  \\ substituting \: y = 1 \: in \: equation \: (2) \\  \\ x = 4y \\  \\ \therefore \: x = 4 \times 1 \\  \\  \huge \orange{ \boxed{\therefore \: x = 4 }} \\  \\ \therefore \: (x, \:  \: y) = (4, \:  \: 1) \\ is \: the \: required \: solution. \\
