Answer:

x = 7, arc DE = 198°

Step-by-step explanation:

Inscribed angles from the same arc are congruent.

∠ DCE and ∠ DWE are inscribed angles from the same arc DE , thus

12x + 15 = 3x + 78 ( subtract 3x from both sides )

9x + 15 = 78 ( subtract 15 from both sides )

9x = 63 ( divide both sides by 9 )

x = 7

Thus

∠ DCE = 12x + 15 = 12(7) + 15 = 84 + 15 = 99°

The inscribed angle DCE is half the measure of its intercepted arc, thus

arc DE = 2 × 99° = 198°

Can anyone teach me how to solve this problem
kati45 [8]
We have constructed two angles with angle measures, 30° and 50° respectively.
Recall the angle sum of a triangle is 180°; the formula for angle sum of any n-sided polygon is formulated by: 180(n - 2), where n is the number of sides.

Since we need the three angles to equal to 180, we can call the third angle x.
Hence, our equation becomes:
 
x + 30 + 50 = 180
x + 80 = 180
x = 100

Thus, our third angle is 100°

Seth’s father is thinking of buying his son a six-month pass for $40. With the pass, matinees cost 1.00. If matinees are normall
mr Goodwill [35]

Answer:

The number of times Seth attend in order for the benefit his father to buy the pass is 2.8 times .

Step-by-step explanation:

Given as :

The price for six month pass = $ 40

The cost of matinees with the pass = $ 1.00

The cost of matinees without pass = $ 3.50

Now, According to question

If we take matinees per day for six months so, number of matinees = 6 × 30 = 180

So, The cost of matinees for six month with pass at the rate $ 1.00 each = 180 × $ 1 + $ 40

I.e The cost of matinees for six month with pass $ 220

Now, Again

The cost of matinees for six month without pass at the rate $ 3.50 each = 180 × $ 3.50

I.e The cost of matinees for six month without pass at the rate $ 3.50 each = $ 630

So, The number of times Seth attend in order for the benefit = \frac{630}{220} = 2.8

Hence  The number of times Seth attend in order for the benefit his father to buy the pass is 2.8 times . Answer
