HELP IN NEED!
laiz [17]

Answer:

AB=12\sqrt{3}\ cm

Step-by-step explanation:

If AB is tangent to the circle, then angle ABO is right angle and triangle AOB is special 30^{\circ}-60^{\circ}-90^{\circ} triangle. In this triangle, the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,

AO=2BO=2\cdot 12=24\ cm.

By the Pythagorean theorem,

AB^2=AO^2-BO^2,\\ \\AB^2=24^2-12^2,\\ \\AB^2=576-144=432,\\ \\AB=12\sqrt{3}\ cm.

Identify the variable(s), set up your equation(s), and solve. Richard has an elder sister who is twice his age and a younger sis
alexdok [17]

Answer:

7 years

Step-by-step explanation:

Given that:

Let Richard's age = x

Elder sister's age = 2x

Youngwr sister's age = x - 2

Product of sisters ages = 70

2x * (x - 2) = 70

2x² - 4x = 70

2x² - 4x - 70 = 0

x² - 2x - 35 = 0

x² - 7x + 5x - 35 = 0

x(x - 7) +5(x - 7) = 0

(x - 7) or (x + 5) = 0

x = 7 or x = - 5

X can't be negative

Hence, x = 7

Richard is 7 years
