Recall that with inscribed angles, they equal half of the arc they create.

Knowing this, take a look at Angle B. Notice that it's two lines are on the diameter? This means that the arc created is 180 degrees. Because it's an inscribed angle, we know that it's 90 degrees.

Also recall that the sum of all angles in a triangle equal 180 degrees.

Knowing this, we can add up all the angles:
(2x + 2) + 9x + 90 = 180

Simplify:
11x + 92 = 180

Subtract:
11x = 88

Divide:
x = 8

Now that we know the value of x is 8, we can input that into the equation of angle 1 in order to solve the question:
2x + 2 = 2(8) + 2

2(8) + 2 = 16 + 2 = 18

Angle 1 is 18 degrees.

the total cost after tax to repair Kimber’s cracked phone is represented by 00.4(30h)+30h Where h represents the number of hours
Serjik [45]

we have that

the total cost is

0.040(30h)+30h

In this equation  the term 30h represent the cost due to h hours at at unit of 30

and the term 0.040(30h) is equal to calculate the 4% of (30h)

so

in this problem the tax rate is equal to 4%

therefore

<u>the answer is</u>

The term 0.040(30h) represents the amount of tax she must pay
