<u>Part 1</u>
By the inscribed angle theorem, arc ZY measures 76 degrees.
<u>Part 2</u>
Since angles inscribed in the same arc are congruent, angle YXZ measures 38 degrees.
<u>Part 3</u>
Since diameters form semicircles and the arc of a semicircle measures 180 degrees, arc XYZ measures 180 degrees.
<u>Part 4</u>
Subtracting arc ZY from arc XYZ, we get 104 degrees.
Answer:
length =3 feet
width = 1feet
Step-by-step explanation:
let the length be x
the width = x-2
area = length * width
3 = x*(x-2)
3 = 
- 2x
(x-3)(x+1)=0
x -3=0
x=3
thus,
the length =x =3 feet
the width =x-2 =3-2 = 1feet
I could help if I had a picture of the problem
89.95 x 0.05 (5%)
=4.4975
The final cost of the DVD player is 89.95-4.4975
=85.4525
≈ $85.45
Answer:
18 inches
Step-by-step explanation:
Rick is building a scale model of the Alamo.
We are given a scale that 3 in. = 15 ft.
The length of the Alamo is 90 feet.
What is the length of the scale model in inches?
So we know that for every 15 feet, 3 inches are actually used in the project and we need a total of 90 feet. To solve, we need to find how many times 15 goes into 90, in which the number it multiplies to will apply to the inches.
15 * ? = 90
90 / 15
6
It takes 15 6 times to get to 90, meaning that we need to multiply 3 inches 6 times to find the actual length of the scale model in inches.
3 * 6
18 inches.
