Answer:

x = 8.2

Step-by-step explanation:

As indicated on the supplied diagram, the measure of arc GH is ...

GH = 360° -83° -115° = 162°

The inscribed angle at F is half this measure, so we have ...

(10x -1)° = 162°/2

10x = 82 . . . . . . . . add 1 and simplify

x = 8.2 . . . . . . . . . divide by 10

Answer: 12a=48

Step-by-step explanation:

4a+6b=10

4a=10-6b

a=(10-6b)/4

a=(5-3b)/2

2a-4b=12

2((5-3b)/2)-4b=12

(5-3b)-4b=12

5-7b=12

-7b=7

b=-1

2a-4b=12

2a-4(-1)=12

2a+4=12

2a=8

a=4

a=4, b=-1

12a=48

Can someone help me please please please

Use the Pythagorean theorem $a^{2} + b^{2} = c^{2}$ to find the missing side length of a right triangle

In this case, after you plug in the given numbers your equation is $12^{2} + y^{2} = 20^{2}$

Then, Just solve that equation for y.

$144 + y^{2} = 400$

$x^{2} = 256$

$\sqrt{} y^{2} = \sqrt{256}$

y = 16

So the answer is B, 16 cm.

I hope this helps, please feel free to ask questions if you're still confused :)
