Answer:

\boxed{

\boxed{

Step-by-step explanation:

A) If AB is a diameter, Then ACB is a 90 degrees angle because In a semi-circle (AB is a diameter which divides the circle into 2 equal parts), the angle opposite to the diameter is of 90 degrees.

So, <ACB = 90 degrees

Then <a = 180-90-28

=> <a = 62 degrees

B) The opposite interior angles of a quadrilateral inscribed in a circle add up to 180 degrees.

So,

=> <a + <b = 180

=> <b = 180-62

=> <b = 118 degrees

Which equation could be used to solve the following system?
nikdorinn [45]

we have

x+y=11

x=11-y --------> equation A

4x^{2} -3y^{2}=8 ----> equation B

Substitute equation A in equation B

4(11-y)^{2} -3y^{2}=8

therefore

<u>the answer is the option B</u>

4(11-y)^{2} -3y^{2}=8

Please help it's fricking urgent
Gwar [14]

Answer:

Kaden had $17 at first

Step-by-step explanation:

Ben = x

Kaden = x - 10

x + 4

x - 10 + 4 = x -6

x - 6 = \frac{7}{9} x

9(x - 6) = 7x

9x - 54 = 7x

2x = 54

x = 27

x - 10 = 27 - 10 = 17
