Answer:

7) 65°
8) 25°

Step-by-step explanation:

Question 7

Angle formed by 2 chords is half of the sum of the intercepted arcs

x = 1/2(72° + 58°) = 1/2(130°) = 65°

Question 8

Angle formed by 2 secants is half of the difference of the intercepted arcs

x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°

$2x-\frac{1}{6}=\frac{2(x-3)}{3}+1\ \ \ \ |multiply\ both\ sides\ by\ 6\\\\6(2x)-6(\frac{1}{6})=6\left(\frac{2x-6}{3}\right)+6(1)\\\\12x-1=2(2x-6)+6\\\\12x-1=2(2x)+2(-6)+6\\\\12x-1=4x-12+6\\\\12x-1=4x-6\ \ \ \ |add\ 1\ to\ both\ sides\\\\12x=4x-5\ \ \ \ \ |subtract\ 4x\ from\ both\ sides\\\\8x=-5\ \ \ \ |divide\ both\ sides\ by\ 8\\\\\boxed{\boxed{x=-\frac{5}{8}}}$

The combined volume of all the tanks at an aquarium is 1.25 X 106 gallons. The aquarium plans to install a new dolphin tank with

1. The combined volume of all the tanks at the aquarium is written in Scientific notation. Keeping this on mind, you can write it as following:

$(1.25)(10^{6})=1,250,000gallons$

2. Now, you must sum the combined volume of all the tanks and the volume of the new tank to calculate the total volume of all of them: $Vt=1,250,000gallons+250,000gallons\\Vt= 1,500,000gallons$
