Find X and Y using the image.

Mathematics
1 answer:
r-ruslan [8.4K]3 years ago

Answer:

x = 59°

y = 130°

Step-by-step explanation:

Find x:

Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem

Therefore,

x = ½(118°)

x = 59°

Find y:

y = 2(180 - (56 + x)) => inscribed angles theorem

Plug in the value of x

y = 2(180 - (56 + 59))

y = 2(180 - 115)

y = 2(65)

y = 130°

The diagram below shows a student using a clinometer to measure the height of a flagpole. When the student stands 40 feet away f
AVprozaik [17]
The correct answer is the flagpole is <span>33 feet high</span>.

Explanation:
Please refer to the attached picture.

We know:
CD = 40 feet
AC = 5 feet
∠BDC = α = 35°

Using trigonometry, we know that the definition of the tangent of an angle is the ratio between the opposite side and the adjacent side, therefore:
tan α = BC / CD

Solving for BC:
BC = CD · <span>tan α
      = 40 </span>· tan (35)
      = 28 feet

In order to find the height of the flagpole, we need to add the distance of the clinometer from the ground:
AB = BC + AC
      = 28 + 5
      = 33

Hence, the flagpole is 33 feet high.

How to change from expo to radical form
Natalka [10]

Answer:

See below.

Step-by-step explanation:

If the exponent is a/b  then a is the power and b is the value of the radical.

Example:   x^2/3  =   ∛x².    2 is the power and 3 is the radical.

Answers:

1)  7^2/3 =  ∛7²

5)  √3 = 3^1/2

9)  (∛27)⁴ = 27^4/3 =  3^4 = 81.

Shelley's basketball team won 3/4 of their games last season. In 1/6 of the games they won, they outscored their opponents by mo
iVinArrow [24]

Let the total number of games be x.

Number of games Shelley's team won = \frac{3}{4} x

Number of games they outscored

their opponents by more than 10 points = \frac{1}{6} × \frac{3}{4} x

= \frac{1}{8} x

Hence, 1/8 of the total games, Shelley's team won by 10 points.
