How do I solve inscribed angles?

Mathematics
1 answer:
Slav-nsk [51]3 years ago
4 0
The triangles are similar so the angles are equal
2x^2 - 2 = 10x - 2
2x^2 - 2 - 10x + 2 = 0
2x^2 - 10x = 0
2x(x - 5) = 0
2x = 0       OR        x - 5 = 0
x = 0         OR        x = 5
0 doesn't make sense, because IF I plug 0 into 2x^2 - 2 I get a negative number.  We need to use 5 to find the angle measure

2(5^2) - 2 = 2(25) - 2 = 50 - 2 = 48 degrees or the measure of CED

McKenzie sells textbooks. She receives 7% on her first $1,000 in sales and 15% on the balance of her sales. How much would she e
Alisiya [41]

The commission would be $2095.

Step-by-step explanation:

Given,

Commission on first $1000 = 7%

Amount of commission = 0.07*1000 = $70

Worth of sold items = $14,500

We will subtract $1000 from it.

Balance = 14500-1000 = $13500

Commission on balance = 15% = 0.15

Amount of commission = 0.15*13500

Amount of commission = $2025

Total commission = 70+2025 = $2095

The commission would be $2095.

A cell phone package charges $39 even if 0 minutes are used during the month. Each additional minute of talk time adds $0.07. Wh
zmey [24]

Answer:

total cost = $ 81

Step-by-step explanation:

It is given that the fixed cost is $ 39

and the cost per minute is $0.07

Let us assume the number of minutes used be x

we have

total cost = cost per minute × number of minutes used  + fixed cost

we plug the given values, so we have

total cost = 0.07 x+39

we need to find the total cost for 10 hours used

x= 10 hours = 10(60) minutes = 600 minutes

so we have total cost for x= 600 minutes

total cost = 0.07(600)+39

total cost =42+39 = 81

hence the total cost = $ 81

The measure of Angle 2 is twelve less than five
hoa [83]

Answer: The measure of Angle 2 = 148°

Step-by-step explanation:

Given: The measure of Angle 2 is twelve less than five  times the measure of Angle 1.

Let the measure of Angle 1 = x

Then, measure of Angle 2 = 5x-12

Since both the angles form linear pair, so their sum = 180°  [linear pair of angles must add up to 180°.]

Then, x+ (5x-12) = 180

⇒ x+ 5x-12= 180

⇒ 6x-12= 180

⇒ 6x= 180+12

⇒ 6x= 192

⇒ x= 32  [divide both sides by 6 ]

So,  measure of Angle 2 = 5(32)-12 = 160-12 = 148°

Hence, the measure of Angle 2 = 148°

The area of a square-shaped rug is 144 ft^2. What is the perimeter, in feet, of the rug?
Nezavi [6.7K]

Answer:

48 feet

Step-by-step explanation:

The rug is a square so that means that the sides are going to be the same length. 12*12 = 144 so the lengths of the sides are 12 feet. 12+12+12+12 = 48

hope this helped! :)
