The answer is 2(7-3x) HAVE A GREAT DAY !!!
Answer:
16
Step-by-step explanation:
We can see that Ar is the perpendicular bisector of chord BD. Since A is the center of the circle, AR is the radius of the circle, which is 10 (6+4)
Next, we can see that when we connect point A to point D, it is also a radius. Thus, AD is also equal to 10 as the radius of the circle remains the same.
Using Pythagoras theorem, a^2 + b^2 = c^2, we can make a right angled triangle of ACD.
AC = 6 = a
CD = ? = b
AD = 10 = c
10^2 = 6^2 + b^2
b^2 = 10^2 - 6^2 = 64
b = CD = 8
Now, since Ar is the perpendicular bisector of chord BD, BD = CD x 2
BD = 8 x 2 = <u>16</u>
Answer:
C
Step-by-step explanation:
Complementary means that the angles have a sum of 90° so we can write:
m∠A + m∠B = 90° → 3x + 2 + 8x = 90
11x + 2 = 90
11x = 88
x = 8 which means that m∠B = 8x = 8 * 8 = 64°.
Supplementary means that the angles have a sum of 180° so m∠C = 180° - m∠B = 180° - 64° = 116°.
Answer:
i=40
Step-by-step explanation:
i is the interest. So to find i we will multiply their pay by the rate.
500 x 8% or .08
500 x .08=40
So the interest of this equation (or i) is 40
